[#INFRA-207] Create repo(s) for varying instrument characteristics

[ I am restating this ticket to include more subsystems. It did not make
sense to only cover detector properties. ]

We are starting to accrete time-variable data which are required for
instrument operations, image simulations, and data reductions. I'd
like to gather a list and see whether we can agree on a small number
of locations for them. And I propose that by default we save them all
in a small number of git repos: pfs_instdata for all, or maybe
spread out to ics_instdata, drp_instdata/obs_pfs,
ics_cobraData.

Here are the products I have thought of and a guess as to how often they will
change. Please propose or directly add any others.

Product	Consumer	Variability	Data Store	Comment
The MCS and FPS distortion coefficients and interpolation tables	FPS, ETS	Annual?	`pfs_instdata`	Most should be very stable, but we already know that there are annual variations. (See also ~~INSTRM-1240~~, but that's an opDB table)
pfsDetectorMaps	DRP	Field?	calib	These are expected to vary with time, but we don't yet know how much or how we will encapsulate the changes. As new versions of the full map, or as a basically static map plus perturbations?
Detector focus motor positions	xcuActor	Warmup?	`pfs_instdata`	These need to be persisted, since we power them down
Slit hexapod positions	enuActor	Stable?	`pfs_instdata`	These need to be persisted, since we power them down
Cobra motion maps	FPS, ETS	Continuously!	opDB	Almost a silly example.
Broken cobra list	FPS, ETS, DRP	Rarely!	`pfs_instdata`	Might be worth tracking on its own?
Cobra x,y of center	ETS, DRP	Rarely	`pfs_instdata`
z-position of science fiber	ETS, DRP	Rarely	`pfs_instdata`
xyz-position of fiducial fiber	ETS, DRP	Rarely	`pfs_instdata`
Broken cable C fibers	ETS, DRP	Continuously	`pfs_instdata`	Already described in broken fiber status bit
Broken cable B fibers	ETS, DRP	Continuously	`pfs_instdata`
Broken cable A fibers	ETS, DRP	Continuously	`pfs_instdata`
Fiber transmission	ETS, DRP	Continuously	`pfs_instdata`	INSTRM-1270 (also may address broken fibers above)
Black dot locations	ETS, DRP	Continuously	`pfs_instdata`	~~INSTRM-1263~~, ~~INSTRM-1242~~ https://github.com/Subaru-PFS/pfs_instdata/blob/master/data/pfi/dot/
Detector and controller voltages	ccdActor, hxActor, agccActor, mcsActor	Stable?	`pfs_instdata`	H4s will certainly differ. MCS probably not. CCDs? AGCCs?
Detector defects	DRP	Stable/Warmup/Regen	calib	These are currently in `obs_pfs`. Would they stay there if we had a data product?
Temperature/cryocooler power setpoints?	xcuActor, agccActor		`pfs_instdata`
Amp gains and readnoises?	DRP or camera actors	Stable	calib	Are we really putting these in headers?
Instrument/component "seasons"			YAML	After a warmup, or reconfiguration, or other physical change/cycle. I'd like to have a declared and published list. Is this the right place? Possibly covered already by existing mechanisms
Lamp line lists?	DRP		`obs_pfs`	`obs_pfs` or a data product? Should not change between lamp changes. Note that the simulator wants actual line strengths
Sky lines	DRP		`pfs_instdata`	Currently maintained in `obs_pfs`
F-star candidate list	DRP	Continuously	target DB	Not quite a calibration product, but needs to be persisted. Location for data still to be determined (INFRA-242)
AG-PFI transformation matrices	ETS	Rarely	`pfs_instdata`	~~INSTRM-1037~~
