TypeA control noise projection is updated in Noise Budgetter.

[Shoda, Yamada]

I updated TypeA control noise in Noise Budgetter.
I included only velocity damping parts:

ITMX: MNY, MNR, IMP, IMY
ETMX: MNP, MNY, MNR, IMP
ITMY: PS MNL, MNY, IMP
ETMY: PS MNL, MNY, IMP

SInce I forgot to measure some TFs, I use other suspension's TF to estimate control noise. Details are following:

ETMX MNY (HPCD) is assumed 2 times larger than ITMX MNY (LPCD).
ETMX MNR (HPCD) is assumed 2 times larger than ITMX MNR (LPCD).
ITMY IMP (LPCD CRY) is assumed same as ITMX IMP (LPCD CRY).
ETMY MNY (HPCD) is assumed same as ITMY MNY (HPCD).

Coil drivers' information is summarized in klog#11038.

I included Quantum noise.
Quantum noise data is /kagra/Dropbox/Subsystems/MIF/NoiseBudget/FPMI/Noises/FPMIQuantumNoise_IBS1.0W_FINESSE1500_4.6throughput.txt.

Also DARM data is the best one (Dec 6th).
