Collate commitment IDs in output of `query packet`

[mzabaluev]

Summary

Collate numerically adjacent commitment IDs in output of query packet subcommands.

Problem Definition

When the set of pending packets on a channel is large and there are many pending commitments with consecutive IDs (which should be expected in normal channel operations), the output may become unfriendly to read for a human.

Proposal

Collate adjacent ID numbers in non-JSON output of commands under query packet, like [100-200, 202, 207].
