Adjusting robot entering/exiting roboport speed

[JamieNyanchi]

Hi! I would like it if there was some way to adjust the speed at which robots enter and exit roboports. I would be fine with it being a utility constant if that makes implementation more feasible.

A while ago, I made this bug report and I think the comments are related to this: viewtopic.php?t=126657 . I have a feeling that the speed at which robots enter/exit actually comes from the period of the hardcoded sine wave function mentioned in the comments. If that is what controls it, then I suppose I'm really asking if the period can be modified as a utility constant.

My use case for this is to use it as part of an update I'm working on for the GTTS mod (https://mods.factorio.com/mod/GTTS). I use this mod when I can't reach 60 UPS normally and want to play without the lag. However, this is one of the few speeds that I can't seem to adjust with what's available on the current API. If I used the mod to play at 6 UPS, for example, the robot entering/exiting speed is 10 times slower than intended. If it was a utility constant, then I could make it match the intended speed.

Thank you for considering!
