Description
This PR aims to address the static coded nature of the maximum speed used for purging in the purge tower. Currently the speed limit is set to 90mm/sec which works well; however speed gains can be made by increasing this if the printer is able to bridge at higher speeds in the wipe tower.
This PR introduces a max speed limit for the purge tower. The existing, as is limits of volumetric flow for the filament and sparse infill speeds are respected. Same for the ramping up of purge speed up to the limit.

Tests
Tested on my V2.4 350 with ERCF successfully with 150mm/sec with no adverse effect on the prime tower stability, while saving a considerable amount of time from the print - in the example above around 4 hours...!
Regression test: Confirmed that option is not visible on BBL printers (X1C profile).
