Adding "fromSecretNumbers" to the Wallet class

[nixer89]

I am getting a lot of questions from new developers which want to build on the XRPL. Mostly they start with having a XUMM wallet and now want to develop something. The most common question is: "How to get the 'secret key' from my XUMM wallet?"

While the XUMM wallet uses SecretNumbers, it does not allow to export the secret key / family seed.

I think it would be nice if the Wallet instance of xrpl.js would offer a "Wallet.fromSecretNumbers" method to make it easier for new developers to start building.

a possible and easy solution could be to import:

import { Utils } from 'xrpl-secret-numbers'

And implement it like this:

That seems reasonable to me, would you be willing to put up a PR for that?

[nixer89]

yes sure, I will do that tomorrow! :-)

Sweet, looking forward to reviewing it :)

Took a while, but finally got this in for the next release of xrpl.js :)
