Set the tempo of the score
The addkey filter adds a key designation of a Humdrum file.
Without options, the addkey tool searches the data for a !!!key:
g:dor, such as for G dorian. This will be inserted as a key
designation in the header, such as *g:dor using this example.
The key designation can be created/change with the -k option
To also set the !!!key: record with the input -k key designation, use -K.

Future enhancements
