Performance + Verbosity of validation + thoroughness of fixing

[oweno-tfwm]

performance: change call from bind to use data.table verbosity: write to console details of the data causing problems during check cleaning: add option to remove 'non-public' services (null route_type) so that the resulting data can load into OTP (and projects like OTP4GB without error) fixing: be more thorough at maintaining referential integrity of output data e.g. ensure that if an agency is missing, data for that agency is removed.

Looks good but I don't understand the removeNonPublic in gtfs_clean can you explain?

[mem48]

Also, I've made some other fixes in main which are causing the tests to fail. Can you pull my fixes into your branch so that we can retest your PR?
