rABCd8bddc7c3fcf: [Cashtab] Upgrade SLPv1 genesis txs

Summary

Have had helper functions in here for awhile but was working on the best way to implement.

For a Genesis tx, I think it's best to preserve the existing SendXec function and simply load it with targetOutputs that match SLP spec. We do not need to select any token utxo inputs for a genesis tx.

Modify getSlpGenesisTargetOutput function to return to-spec target outputs for a fixed supply genesis tx. Implement in CreateTokenForm.js.

The resulting tx differs from the legacy tested tx only in having a better calculated fee.

Test Plan

npm test

npm start and create an etoken with an icon to make sure this works (or trust me on this one, I did it and it does work)

cashtab/src/components/Etokens/__tests__/CreateTokenForm.test.js
74 ↗	(On Diff #45461)	old one loaded in electrum, change is 9501.52
74 ↗	(On Diff #45461)	updated tx, change is 9503.11 (better fee calc) -- otherwise the same
cashtab/src/slpv1/__tests__/index.test.js
29 ↗	(On Diff #45461)	txBuilder takes a buffer for script, which is complicated to store in JSON mocks. So, we test the function result against script.toString('hex'), same as before.
