Release v1.0.4

Version 1.0.4
6th December 2023 changes

1.No longer required to manually create configuration csv files.
Checks if csv files exist and creates them if they do not exist.
Default values can still be edited in csv files but also in the configurations dictionary at the start of the code.
Default keywords changed to lower case
To ensure csv edits don't cause issues the data read from files is:
stripped of leading and trailing spaces
keywords are converted to upper case to match FITS header keywords
column names are converted to lower case to ensure code can work with them
corrected data frames are saved back to csv files to format issues are resolved
2. Improved extract header function
converts floats to 4 decimal places
converts dates to format %Y-%m-%d, rounds input to microseconds to ensure conversion works
creates a subset of the header data that matches AstroBin requirements
3.Sites.csv file latitudes and longitudes saved with 4 decimal places but processed to 2 decimal
places to ensure the same site is not recorded multiple times.
4. Corrected issue with Bortle and SQM values not being updated correctly
5. Corrected issue with Keywords from .XISF files not being read correctly
6. Improved code to correct file data reading and saving logic
7. Runtime option to stop program if new csv files are created to edit them.
8. Corrected program logic related to import, access and storage of external parmeters.
9. Refactored code to improve readability
10. Updated docstrings
11. Works with files generated by both Sequence Generator Pro (SGP) and NINA (.FITS, .FIT, .FTS, .XISF)
12. Looks for filter in FITS headers and converts them to 5 digit codes used by AstroBin ( use to be four digit codes)
