FIT: add RecPoint reader and writer workflows for FV0 and FDD

[andreasmolander]

The main purpose of the commit:

• Adding workflows for reading RecPoints for FV0 and FDD, these are needed for MC aQC

Secondary purposes that arose during development:

• ROOT macro for comparing two RecPoint files
• Workflows for writing RecPoints added for FT0, FV0 and FDD (i.e. simply standalone RecPoint writers, not related to reconstrucion)
• The two items above were needed to verify the new RecPoint reader workflows, namely by: reconstructing CTFs -> writing RecPoints to file -> Reading RecPoints from file -> Writing RecPoints to new file -> Comparing the two files
• Minor cosmetics (e.g. reordering of includes) and utility functions (print and == operator functions)
