Don't bundle the store

[Rich-Harris]

#2733 switched the store to TypeScript and started bundling it, which has unintended consequences. It needs to be converted from TS, but should otherwise remain unbundled

Is there a fix for this ? Should roll up be configured to exclude store?

This seems to do it but gosh is it hacky.

For the record: another thing i tried is compilation using tsc to produce unbundled versions of the store. However the compilation is slow and the internal path becomes invalid because it is unaware of the rollup path changes:

tsc -m es2015 -d src/store.ts --outDir . && mv store.js store.mjs
tsc -m commonjs src/store.ts --outDir .

Fixed in #2842
