Dump command

Print pitches of a scale:

• tune dump rank2 3/2 3 4

Print the scl format to a file directly:

• tune scl -o output-file.scl equal 1:22:2

The CLI for rank2 temperaments is more sound:

• Use tune scl rank2 1:4:5 6 1 instead of tune scl rank2 1:4:5 7 -o-1

tune can now be used as a library
