Add create-stake command to solana-tokens CLI

[garious]

Problem

When we created the solana-tokens CLI, we only had locked up tokens and so the distribute-stake command requires a source stake account to split up and a lockup authority signer to change the target accounts' lockup dates. Now that we have unlocked tokens, it is tedious to manually move tokens into stake accounts just so solana-tokens can split them. Instead, it can skip the split and just create the stake accounts directly.

Summary of Changes

Add create-stake command to solana-tokens CLI. It uses the --from System account to both send the recipient SOL for fees and to fund the new stake accounts. Unlike the distribute-stake stake command, it does not require a source stake account or a lockup authority signer.

Hold off on reviewing. The implementation can be simpler and I'll play with integrating this functionality into one of the existing commands.

@CriesofCarrots @danpaul000, ready for review. Something to consider: we could merge the distribute-tokens and create-stake commands by making the rule that if a lockup date is in the input CSV file, then it should create a stake account. That'd also mean that the output CSV file would contain a blank column of new_stake_account_address when that feature is not used, which might seem weird. For now, I'm thinking we should just let separate things be separate.

@CriesofCarrots @danpaul000, wdyt?

Generally looks good, but one missing cli Arg.

For now, I'm thinking we should just let separate things be separate.

Agreed, I like the commands being explicit, although I do think distribute-stake is a little ambiguous now. Fine for now, though.
