fix: updates for latest multiformats

[rvagg]

this needs the newer types dist changes migrated from multiformats when finalised there

[rvagg]

this is against multiformats/js-multiformats#70, so won't pass until that's published

======== Module name 'multiformats/cid' was not resolved. ========

Looks like it does typeVersions resolution twice and fails to resolve for that reason, which reminds me of the that or similar issue I've reported in the past microsoft/TypeScript#41284

Now that we know what is failing, we can try finding a work around

[Gozala]

I have tried my best to get this resolved but it seems there is a combination of bugs that either breaks js-car or breaks ts-use example in js-multiformats. If we do use * in typeVersions and types field that runs into microsoft/TypeScript#41284

If we do not use types field all the modules resolve except for multiformats.

If we do use multiformats/* pattern in multiformats it works here, but it breaks usage from project that is written in TS as our test in the multiformats repo

At this point I'm not sure if there is a reasonable way to get any of this to work

[Gozala]

Found a workaround and submitted multiformats/js-multiformats#72

[rvagg]

Pulled in the enhancement from #8 to here, also copied an additional enhancement from multiformats/js-multiformats#70 that fixes the *.ts.map files by copying in source (and tests in this case) into the dist and running tsc in there. The maps come out nicely, the published asset includes all the things (my preference!) including examples, original source (with comments and types) and tests.

Will update when multiformats/js-multiformats#70 is done and copy the same enhancements to the codecs.

[rvagg]

This is passing now with multiformats@6.0.0 as per multiformats/js-multiformats#70

I'm pretty happy with the pattern emerging here, it seems to be ticking the boxes we care about as far as I can tell.

[rvagg]

updated to today's multiformats and codecs, removed a bunch of ts-ignores, expanded typing checking and improved the published version a little 🤞
