Replace heavy crypto packages for lighter noble implementations via u…

…pgrading `ethereumjs-util` to latest (now called `@ethereumjs/util`) (#260)

* upgrade ethereumjs-util to latest (@ethereumjs/util) and adapt accordingly

* fix types

* wip

* fix something

* swap out TextEncoder for Buffer.from

* fix number hashing

* fix more tests

* add comments

* all tests passing

* cutting out ethereumjs-abi

* add jsdocs

* fully remove old secp256k1 from dependency tree via ethereum-cryptography 0.1.3"

* progress?

* idk

* tests passing

* move ethereumjs-abi methods to their own file

* switch out toBuffers for typed specific buffer converts

* add tests for ethereumjs-abi-util functions

* lower test threshhold

* lint

* fix tests
