This allows the plugin to be configured to run on an allowlist, rather
than compiling all files helping with an incremental rollout plan.
The sources option takes both an array of path strings or a function
to be flexible.
For now I've left this be optional but we can make it required.

No need to commit this in the repo, but keeping this locally helps with
building the feedback repo.

The compiler has an optimisation where it transforms a simple arrow
function with only a return statement to a implicit arrow function.
In the case, there's a directive in this simple arrow function, the
directive gets dropped.
Instead of dropping the directive, the compiler should perform this
optimisation only if there are no directives.

To make the polyfill work well with devtools, we add this sentinel.
Devtools will look for this sentinel before adding the Forget badge.

Fixes a tiny inconsistency with compiler options where one was all
uppercase and one all lowercase by normalizing to lowercase regardless
of the casing of the user's config.

It was never clear to me what the difference between Wipe and Reset was.
Let's just get rid of one and reset to something more useful instead of
fibonacci.

This compresses more efficiently than the base64 encoding we were
previously using, which makes sharing URLs a little less unwieldy and
takes up less space in local storage. Using
some real code as an example, lz-string compresses to 8040 bytes,
whereas the original base64 encoding we were using compresses to 16504
bytes

CannotPreserveMemoization
We do need to fix the error location to point to the "callsite" rather
than the definition of the useMemo callback, but that aside, even if the
error message were perfect, it's not meant to be actionable to the user.
So let's change the severity to CannotPreserveMemoization. This
preserves the validation, but the eslint plugin won't report it.

This adds a new category of error where the compiler cannot preserve
memoization exactly how as it was originally authored. We're adding a
new category here because it's not an actionable error, and allows us to
more specifically control whether it's reportable or not.

First attempt at making the linter work with advanced TypeScript syntax
Falls back to the babel parser for some advanced syntax like string template
syntax.
This is pretty hacky as it doesn't take in any parsing options that are
configured for the outer ESLint parser, not sure how that could be handled.
Implements support for use:
* Teaches InferReactivePlaces to treat use() result as reactive
* Teaches FlattenScopesWithHooks to also flatten scopes with use()
Handles both `use()` and `React.use()`.
This adds rollup to the runtime and adds a new plugin to add the license banner
+ inject the `"use no memo"` directive. We need to inject it there as rollup
currently strips out unknown directives during bundling.
For now this configures rollup to strip out comments in DEV builds and
whitespace. Unfortunately there's no easy way to do this in just terser alone or
other minifiers/manglers, so I had to add prettier as well to re-format the
minified code. This does make the build a little bit slower:
``` before: yarn build 118.96s user 12.38s system 185% cpu 1:10.81 total after:
yarn build 121.55s user 12.90s system 183% cpu 1:13.17 total ```
Eventually I would like to have a similar setup to React's rollup config where
we can have DEV and prod builds. After the repo merge we could probably share or
reuse bits of React's rollup config.
