fix: replace node buffers with uint8arrays (#730)

* fix: replace node buffers with uint8arrays

Upgrades all deps and replaces all use of node Buffers with Uint8Arrays

BREAKING CHANGES:

- All deps used by this module now use Uint8Arrays in place of node Buffers

* chore: browser fixes

* chore: remove .only

* chore: stringify uint8array before parsing

* chore: update interop suite

* chore: remove ts from build command

* chore: update deps

* fix: update records to use uint8array

* chore: fix lint

* chore: update deps
