Add Pedal Brackets

Dear Noteflight Team,

There is already a way to include damper pedal in songs for piano, however, I would like to include a way to make brackets that look like |___^____| I feel like this would be very helpful and more clear than leo_____*.

On top of that, including una corda in a similar format would also be helpful. It would look like this una corda_______tre corda.

I hope you will be able to make this happen
