Bug fixes and new sensor - beta release

Bugfixes

• Draft fix (actually related to the associated PyTransportNSWv2 module) where the origin filter was also being applied to the destination (#22)
• Fixed a strange issue when 'all' (value 0) actually got written into the config entry options, instead of the numeric options themselves, which goes on to break ConfigFlow (#23)
• Reconfiguring the API key wasn't updating the entry title or the unique ID (#26)
• Fixed future sensors not being created if the user has 'all possible sensors' selected
• Reduced the minimum wait time to 0 minutes (thanks @dancmorgan!)

New sensor

• Added the option of showing the train set type, eg Waratah or Tangara (#24)

New filter

• Journeys can now be filtered out if they have too many changes - always get the direct train if you want! (#28)
