invalid reverts in puzzle 10

[charles-cooper]

In https://github.com/fvictorio/evm-puzzles/blob/c98de5c51062648680cc55d6dac84bc6792b40dc/puzzles/puzzle_10.json#L2, there are several REVERT instructions, but since there aren't enough items on the stack, they don't actually revert, I think they trigger an exceptional halting state (same as 0xFE INVALID). For clarity, maybe these instructions should be changed to 0xFE - or start the code with MSIZE MSIZE so that the REVERT opcodes will have enough stack items to consume!

Oops, you're right, I should've used 0xFE. I'll change that, thank you!
