Allow mint submissions as start block is pending

[coinspiracynut]

Current implementation only allows mint submissions after the start block is confirmed meaning ord users can not attempt to compete in that block. This implementation allows for submissions at start - 1, which is a good solution for most users. However, a flag to ignore these checks for power users might be a more composable solution.

Isn't the end check similarly off by one?

If the minting ends at block 80 and block 79 is the current block, new mints won't be accepted in block 80 so don't let people mint after block 79 has been mined
