Assert size of seed and hashes for obfuscation is within bounds
Assert size of seed and hashes for obfuscation is within bounds

The standard input, a base58-encoded pubkeyhash, for the obfuscation
has a size of at most 35 characters, and the hexified SHA256 hashes
have a size of 64 characters, which is both within the bounds of the
arrays used during the obfuscation.

This change enforces these conditions and ensures the input, and hash
results are guaranteed within bounds.
