Standardize sensor type across all tags

[peterdesmet]

Archival tags use a controlled vocabulary for sensor type, while acoustic tags do not. It would be best if all tags use the same controlled vocab. Will be easier once all tabs share the same table (see #192). Currently:

   tag_type          sensor_type     n
   <chr>             <chr>       <int>
 1 acoustic          P               1
 2 acoustic          NA          10589
 3 acoustic,archival A             286
 4 acoustic,archival P             806
 5 acoustic,archival P, M          179
 6 acoustic,archival pressure      187
 7 acoustic,archival T              89
 8 acoustic,archival temperature   187
 9 acoustic,archival T,P           120
10 acoustic,archival T, P          105
11 archival          pressure      207
12 archival          temperature   207
