Parameter to ignore restrictions (access, hgv, ..)

[TheGreatRefrigerator]

When calculating routes or areas of accessibility for e.g. emergency vehicles (fire brigade, ambulance), this is often limited by
access or hgv restrictions.
Currently, the only option is to run a local instance and create a new Profile/FlagEncoder which disables the restricitons.

A parameter for disabling restrictions for specific tags might be useful in those cases.

On the api side it could be a parameter like ignore_restrictions:["access", "hgv", ..]
The response should probably contain a warning that in accessible parts might be contained in the route / isochrone.
