Generate and store all supported microdescriptor formats. Generate votes with one "m" line for each format. Only "m" lines with version info matching chosen consensus method will be voted upon. An optimisation would be to combine "m" lines with identical hashes, i.e. instead of "m 1,2,3 H1" and "m 4,5 H1", say "m 1,2,3,4,5 H1".
