More control for spidertron bobbing and height

[snouz]

Hi, I would like to suggest being able to control several things about the spider-vehicle prototype
https://lua-api.factorio.com/latest/pro ... otype.html

Right now, we have access to: height, torso_rotation_speed and torso_bob_speed.

Request:
I would love to be able to control:
- different settings when the spider is in movement / idle
- bobbing strength (height)

Suggested new interfaces:
- torso_height_idle (float)
- torso_height_moving (float)
- torso_bob_speed_idle (float)
- torso_bob_speed_moving (float)
- torso_bob_height_idle (float)
- torso_bob_height_moving (float)

And ideally, we could go even further and suggest:
- height_idle_delay (in ticks) -> adding a configurable time until the spider lays down
- height_idle_transition_time (in ticks) -> how much time it takes to switch between idle and moving visual states
- torso_height_speed_multiplier (speed affects the height of the torso, default 1)

Use case

This could see great use for mods like this. This would make it possible for spiders (and vehicles that use that prototype) to ground themselves, which could add life to them, add diversity, and in the case of lex aircrafts, having the aircraft actually land.

+1, having more avenues to control spidertrons and their movement would be nice
