rABC028567a5502f: [Cashtab] [BCH deprecation] [TxBuilder] Pt 1/8 - Localize Transaction Building…

Summary

T2730

This diff creates a local transaction builder module to localize the bch-js portion of the transaction building process.

Temporary comparison checks have been added to sendXec which verifies that the txBuilder object matches after each stage of adding input, output and signing/building tx.

Relies on bitcoincashjs-lib for the eventual transaction building, and bip66 and bc-bip68 as per bch-js.

Pt 1/8 - Localize Transaction Builder module
Pt 2/8 - Deprecate BCH.TransactionBuilder in sendXec
Pt 3/8 - Add local TxBuilder to createToken
Pt 4/8 - Deprecate BCH.TransactionBuilder in createToken
Pt 5/8 - Add local TxBuilder to sendToken
Pt 6/8 - Deprecate BCH.TransactionBuilder in sendToken
Pt 7/8 - Add local TxBuilder to burnToken
Pt 8/8 - Deprecate BCH.TransactionBuilder in burnToken

Test Plan

npm ci
npm test and ensure no errors with txBuilder.test.js
npm start
send a one to one XEC tx and ensure the post-generateTxInput() output matches, post-generateTxOutput() output matches & post-signAndBuildTx() output matches console log messages are displayed
send a one to one XEC tx with an unencrypted message and ensure the same 3 console logs from above are displayed
send a one to one XEC tx with an encrypted message and ensure the same 3 console logs are displayed, and the message is decrypted on the receiver side
send a one to many XEC tx and ensure the same 3 console logs are displayed
send a one to many XEC tx with an unencrypted message and ensure the same 3 console logs are displayed
send an airdrop one to many XEC tx and ensure the same 3 console logs are displayed
send an airdrop one to many XEC tx with an unencrypted message and ensure the same 3 console logs are displayed

Note, reviewer should use npm ci instead of npm i, to ensure that package-lock.json is not overwritten

At some point in the future we will want to move coininfo and this new TransactionBuilder out of cashtab utils and into its own module. However, I think it's okay for them to live here now, since Cashtab is the workshop for determining what needs to be adjusted / improved for these libraries to make more sense in XEC development.
