Material Mining Speed problem

[worthy cargo]

There is a discrepancy between the displayed mining rate of Material Gatherers and the actual mining output.

By default, they mine at roughly 90% efficiency,
and when time is accelerated to 10x speed, mining drops to about 50–60% efficiency.

With 10 Material Gatherers,
the theoretical output should be 216,000 materials per hour.

However, in practice, the actual output is:

At 1x speed: 194,400
At 10x speed: 108,000–129,600

This issue occurs consistently in the official campaigns NETER, AOTE, and GLAO,
as well as in CC.

It also affects both the player and factions equally.

(The same issue occurs even when using Electric Engines or RTG Engines, so no materials are being consumed by engine usage.)

I've put a fix in for this. That I hope doesn't explode everything 😛

@boreal pewter if you could test this if you have a moment.

It's actually a fairly big issue across multiple things not just mat gatherers

Will test it out tomorrow, have to leave very soon
