Allow specifying subsecond granularity with tshark -t
Implements suggestion in issue #18714.
Proposed syntax for setting subsecond precision is "tshark -t adoy.3" for
millisecond accuracy in output. Using a dot separator indicates the precision
of what follows the dot in the output.
The following tshark -t combinations are supported:
1. Specifying just the format with e.g. "-t a" and defaulting the precision.
2. Specifying both format and precision, with "-t ad.2" or "-t ad -t .2".
3. Specifying only the precision with "-t .6" and defaulting format.
4. Use "-t a." or even "-t ." to specify auto precision from trace.
The latter use case is particularly useful with wireshark/logray.
Using a dot like this avoids introducing a new command line option.
