Removal of sqlite/sqlalchemy based approach - it is too slow to combine the results, even with in-memory database loading.

Improved a few things, querying for multiple services now runs at a tolerable speed. Would prefer if it could be improved further, will look at pre-merging tables using sql rather than pandas.

Begun creating some utility functions and noticed some limitations. Fetching one schedule at a time is too slow, and we could easily split an aggregated result.

Various minor updates, basic Schedule class. Added a SixData class to manage conversions of YYMMDD to/from more pythonic objects.

Added mca_queries.py and it's pre-generated result mca_record_types.py. The latter is for type hinting and will make writing queries to solve for schedule numbers much easier. Next will be to write tools to make hunting for desired schedules easier.

Updated the raw_mca_... table generation to include line number from the file, and schedule number - although we may need to investigate how the last entry behaves with 'ZZ' records and any others. We don't want to inherit the technical debt of remembering this one case every time.

Finished parsing.py initial implementation, now have a sqlite database generating >600MB of timetable records. Next will be generating sqlalchemy desriptors based on the automated specifications. If I can re-learn sqlalchemy that is.

Added sqlite export of .MCA file's record spec. This won't live in /data, but in a user's cache. This is to allow user choice on how and when to update the timetable files and reduce redundancy.

Parsing of RSP's specification now cached to /data. This means that we can ship the tables with the project, rather than the .pdf being a requirement of use.

Used pypdf to create extract_specification_document_tables in parsing.py. Should allow easier indexing of the various file types in future. Will need to adapt for files other than .MCA and look at formalising into a local database.
