Remove `lodash` from the xrpl package about xrpl.js

[ckniffen]

@develoQ I am up for removing lodash all together if the methods used can be done in modern js.

[ckniffen]

Done as part of 3.0

@ckniffen Exactly, most things are very easy with some map/reduce/filter/... these days.

I believe I tried to remove as much lodash as possible at some point, but in some places there were really nice functions like groupby and omitby that were hard to replace.

[WietseWind]

groupby would be very easy with a reduce fn?

Ugly piece of code, idea is clear, reducer could be a more generic fn of course.

const people = [
  { name: 'Nienke', gender: 'F' },
  { name: 'Wietse', gender: 'M' },
  { name: 'Arwen', gender: 'F' },
  { name: 'Quinn', gender: 'M' },
]

const sortedPeople = people.reduce((a, b) => {
  if (!a[b.gender]) {
    Object.assign(a, { [b.gender]: [] })
  }
  a[b.gender].push(b)
  return a
}, {})

@develoQ @intelliot is it done. I am keen in learning xrp and want to pick this

[ckniffen]

@aruns05 when working on this the solution should reduce the webpack bundle size.

[ckniffen]

@aruns05 I went ahead and did this as part of our effort to reduce the bundle size of xrpl.js. Let me know if I missed anything in #2378.

There will be more PRs to reduce size in the next few weeks.
