This is the last PR with lots of renaming for `loot-core`!

Another batch of `loot-core` migrated.

Another batch of files from `loot-core` migrated to TS (loose mode)

This PR converts everything (aside from electron) from CommonJS to ESM.
It is needed to reduce the changes that will happen during the migration
to Typescript (as TS does not play nice with CJS).

Basically:
- rewrite `require()` to `import`
- rewrite `module.exports` to `exports`
- introduce `ts-node` to run importers so we can convert them to TS too

Lastly, sorry for this larg-ish PR, not my preference but when I tried
to reduce its scope, I would end up with mixed commons/esm that was even
more tricky to handle.

Fixes #840 by creating application-defined SQL functions
(https://www.sqlite.org/appfunc.html) for Unicode-aware implementations
of `LOWER()` and `UPPER()`. This uses
`String.prototype.toLower/UpperCase()` JS method.

I initially wanted to just redefine `LOWER()` and `UPPER()` but due to
[sql.js not supporting the definition of deterministic
functions](https://github.com/sql-js/sql.js/issues/551), I had to just
define them as separate functions and use that in the appropriate
places. It's probably better like that anyway...

Part 1 of the conversion. Mostly renaming js to ts and making sure
things make still sense. Added also handy TS ESLint rules.

In order to support the various .web/.electron/... I ended up adopting
`index.d.ts` as pattern to share type definition. Let me know if that
makes sense for you too. Right now the function type definition is
duplicated, but the solution will be importing from `index.d.ts` and
using `const fn: FnDef = () => ...` that way we can keep all variants in
sync from a single type file.

Such rewrite however is better done in another PR otherwise we risk
confusing git and loosing history (rename + too many changes). Another
thing that might do in the next PR is convert all files to ESModules, as
things get confusing between CJS exports, ESM default/named and TS adds
extra complains.
