Proposed Changes

Implements 2 improvements to the compact partitions command:

• Auto split into smaller messages as needed, if a single message wouldn't fit in a block
• Simulate if really-do-it isn't passed, reporting on the gas costs

Additional Info

• Needs feat: API: support typed errors over RPC #9061

@jennijuju Unsure whether or not changes are needed here, thoughts?

Just tested this, by trying to compact a single partition deadline, and the simulation of the message looks nice:

lotus-miner sectors compact-partitions --deadline 0 --partitions 0
compacting 1 paritions
total of 1 CompactPartitions msgs would be sent
msg 0 would cost up to 3175283136060

Two small UX-improvements could have been to print the potential gas cost in a more understandable format, and print msg 1 instead of msg 0 😄

I don't see any reason not to ship this
