Description

A output's script may be bigger than 10k bytes, it just can't be spent. We incorrectly check the script pubkey size when it gets created, causing floresta to break out of consensus if such an output is mined.

Fixes #393

Notes to the reviewers

Tests for this will be integrated on #387

ACK. So large outputs are simply not added to the acc, and the 10k limit is enforced for scriptsigs.

Yes! It could be created, but never spent.
