feat: Adapt position update interval of darwin, linux, web

[Gustl22]

Description

• Linux: changed update interval from 1000ms to 250ms
• Web: position was rounded to 1s as its handed over as float, now it's multiplied with 1000 to profit from millisecond precision, update interval is still dependent on browser implementation
• Darwin: changed update interval from 0.2ms to 200ms, which most probably was a mistake and caused much overhead
