Allow longer exposure times

[albireox]

This PR fixes an issue that prevented exposure times longer than 1000 seconds.

Parameters in the Archon language cannot have values larger than one million. Since the exposure time was set in milliseconds, a 1000 seconds exposure was 1,000,000 milliseconds and thus the limit. This PR introduces a breaking change in which we set the exposure time in centiseconds (yes, centiseconds) allowing exposure times of up to 10,000 seconds. This requires changing the ACF files that work with Archon to use a new IntCS parameter which stores the integration time in centiseconds. Then we need to change from

X; CALL IntUnit(IntMS)

to

X; CALL IntUnitCS(IntCS)

and add a new function

IntUnitCS:
X; CALL IntUnit(10)
X; RETURN IntUnitCS

All in all this is not a super satisfying solution but it's unlikely we need exposure times longer than 10,000 seconds and any other solution would either be limiting (for example setting the exposure time in seconds, which would limit us to an integer number of seconds) or more complicated (e.g., adding an additional parameter in which we count the number of times the IntMS variables goes over one million).
