add name decoding.... oh and remove jest testing >_>

[Pomax]

This adds name table string decoding based on platform and encoding id, albeit only limited to mac, shift jis, and big5. Everything else is currently still considered "then it must be regular text already".

This PR also strips out Jest because it's horrendously out of date and just makes tests that use modern JS break (it literally broke every test because whatever it does, that doesn't support new TextDecoder()).

And of course for good measure this adds a test that confirms the name string from the IBM Plex Sans Thai font actually matches Mike Abbink, Paul van der Laan, Pieter van Rosmalen, Ben Mitchell, Mark Frömberg with the o-umlaut in Frömberg.

partially addresses #85

@RoelN want to give this a spin?

[RoelN]

I saw one test was failing because we tested against the "old" wrong characters. Took the liberty to update this, and also update lib-font.browser.js since we bundle this into the repo.

Thanks for implementing this!

Will you bump the version and do a new release?

PS. I take it you say it partially addresses #85 as we don't technically do all encodings?

[Pomax]

Correct - in order to support the full set of platform/language/encoding sets, we'd need to do a bunch more work because TextDecoder doesn't have those baked in =)
