Do not hardcode bikes_allowed for Muni

[hcourt]

It would be a good idea to no longer hardcode these data fixes in Trip.java. In the mid term, by having some pre-build step that uses https://github.com/interline-io/transitland-lib to fix data. In the long term, by fixing the data in the GTFS feed itself.

I was drafting an email to the 511 developer Google Group to get the upstream data fixed. However, I just read that foldable bicycles are allowed on LRVs, hence probably why we see bikes_allowed=0 for those associated routes (it's ambiguous).

But not on cable cars, which also have the field left empty. They could at least set bikes_allowed to 2 for those. I would also argue folding bicycles are not the common case.
