Add support for art v2_11_05 (s73)
Mu2e has requested artdaq support for art v2_11_05, the s73 qualifier.
artdaq already supports the v2_11 series of art through the s67 qualifier.
I have performed basic testing as follows:
- artdaq's develop branch builds against s73 with no code changes
- All unit tests complete successfully
- The demo runs and produces data files which can be read using rawEventDump and toyDump
- art v2_11_01 (s67) can read the data file produced by s73
