If you redirect the stdout/stderr from Forc to something other than a tty you're still going to have ANSI escape codes for coloring:

❯ forc build |& cat --show-all
^[[0m^[[32m  Compiled library "core".$
^[[0m^[[0m^[[32m  Compiled library "std".$
^[[0m^[[0m^[[32m  Compiled contract "transaction_block_height".$
^[[0m  Bytecode size is 84 bytes.$

The convention for CLI tools is to check (via isatty) if what you're writing to is a tty before using escape codes.

Cargo also provides a --color flag for controlling this, we might want to consider doing something similar too.

We should consider addressing #2373 first as it would simplify adding an isatty check.
