Draft: Test full naming sequence by chaining `addJob` and `generateFilename` in prep of #54

Test full naming sequence by chaining addJob and generateFilename

Outside of addJob and generateFilename, had to manually:

• sanitize targetName
• construct the directory part of the path by concatenating
  • SequenceJob::localDirectory
  • SequenceJob::directoryPostfix

The test is done in TestPlaceholderPath::testFullNamingSequence. Comparison between the generated path and results had to be change to a regex match because of the varying path result:

• the path can now include a date because of the TimeStampEnabled parameter. The regex used to match a date is \d{4}-\d{2}-\d{2}T\d{2}-\d{2}-\d{2}.
• Options::fitsDir() from kstars/ekos/capture/placeholderpath.cpp:206 results my home directory. The regex used to match it is .*.
• The whole regex is enclosed in ^myregx$ to match the total string.
• . dots in the path are escaped: \.
