Remove lodash from the xrpl package

[tequdev]

When connecting to XRPL with Metamask Snap, due to a Hardend Javascript (SES) limitation, xrpl.js cannot be used (resulting in an error).

This is due to the lodash package.

After replacing the lodash package with just, the error no longer occurs, but I am not sure if this package can be included in xrpl.js.

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

@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.

Done as part of 3.0
