"lodash": "^4.17.20"

It's an enormous dependency that hasn't had a release since 2021. How much of it is even needed? _.includes is just a standard array method now. is-what can be imported for helpers like _.isObject. _.shuffle is replaceable by just-shuffle

Yes, it's an unneeded dependency, but is prolific throughout the repo. I've been removing lodash as I go.

One wrinkle. Won't removing this be a breaking change requiring a major version bump? Maybe it'd be a good idea to remove all of these, actually...

	// dependencies, subject to change
	bitcore.deps = {};
	bitcore.deps.bnjs = require('bn.js');
	bitcore.deps.bs58 = require('bs58');
	bitcore.deps.Buffer = Buffer;
	bitcore.deps.elliptic = require('elliptic');
	bitcore.deps._ = require('lodash');

Most of those lines have been there untouched since 2014. #1040
