Update Parser to handle use of Type 7 getStatus commands for DASH

[marionbarker]

As explained in this comment for OmniBLE PR 138, the DASH PDM uses the Type 7 getStatus commands for DASH almost exclusively. This usage will be incorporated in the OmniBLE repository when PR 138 is merged.

The parser is updated to distinguish and count the instances of 0x0e00 and 0x0e07 used by an OS-AID app when controlling the DASH pods as well as other types for 0x0e commands. This is useful while testing PR 138 because it handles the type 0 and type 7 instances separately in terms of msgMeaning and counting the number of each type.

While modifying the parser to handle 0x0e07 commands, fix a few other items that have been hanging around:

• modify the description to be "App Sent" instead of "Loop Sent"
• modify the description for DASH zero temp basal rates to be 0.00 U/hr (the actual command for DASH is 0.02 U/hr to enable a zero temp)
• update units to be U or U/hr (not u or u/hr)
• update some formatting for tables
• add information about sent vs received for FAX (aka Trio) files
