feat: implement isomorphic utils for nodejs and browser

[twoeths]

Motivation

• implement isomorphic utils for nodejs and browser
• try nodejs first, if not use browser version

Description

• the 3 utils are: toHex, toRootHex and fromHex
  • remove from bytes.ts, implement nodejs and browser versions
• the browser version follows toHexString util: try String.fromCharCode api ssz#277
• deprecate toHexString
• tests are scanned through browser tests in this package, perf tests are included

bytes utils
    ✔ nodejs block root to RootHex using toHex                             6396520 ops/s    156.3350 ns/op        -       3868 runs  0.765 s
    ✔ nodejs block root to RootHex using toRootHex                         9505523 ops/s    105.2020 ns/op        -       6710 runs  0.812 s
    ✔ browser block root to RootHex using the deprecated toHexString       3742921 ops/s    267.1710 ns/op        -       1891 runs  0.797 s
    ✔ browser block root to RootHex using toHex                            5582008 ops/s    179.1470 ns/op        -       1690 runs  0.487 s
    ✔ browser block root to RootHex using toRootHex                        6455194 ops/s    154.9140 ns/op        -       2605 runs  0.562 s

related to ChainSafe/ssz#283

this only implement the utils, need multiple PRs to consume this work

LGTM - we might be able to not load nodejs files at all in browser environments but this PR already nicely separates the implementations

we might be able to not load nodejs files at all in browser environments

Was looking into using isomorphic exports / imports but this pattern mostly makes sense if more implementations are environment specific, otherwise it requires to duplicate the exports which might not be worth right now.

But I think if we add more platform specific implementation it makes sense to use a similar approach in the BLS module package.json#L10-L13
