[Feature Request] aptos move coverage needs to be provide useful output when piped to a file

[brmataptos]

🚀 Feature Request

To reproduce:

cd aptos-move/move-examples/veiled_coin
aptos move test --coverage --named-addresses 'veiled_coin=0x424'
aptos move coverage source --named-addresses 'veiled_coin=0x424' --module veiled_coin

Ok, the output has color showing lines that presumably show lines covered (green) or not (red).

But pipe that to a file, or even the less command, and the color goes away, leaving this command pretty useless

aptos move coverage source --named-addresses 'veiled_coin=0x424' --module veiled_coin |& less -P
aptos move coverage source --named-addresses 'veiled_coin=0x424' --module veiled_coin >& test.out

We also should have a non-color output to handle people with visual issues.
