Data for L1 MET and JUMP

[JunwonTomOh]

This PR adds JSON data files to support the externalization of constants used by the L1 MET emulator and the JUMP algorithm, in support of: cms-sw/cmssw#48308.

In particular:

L1Trigger/Phase2L1ParticleFlow/data/met/l1met_ptphi2pxpy_poly2_v1.json

2nd-order polynomial coefficients for the pt,phi→px,py projection

phi_edges (radians, 16 bins → 17 edges), cos2.par{0,1,2}, sin2.par{0,1,2}

includes version, description, and phi_bins metadata

L1Trigger/Phase2L1ParticleFlow/data/met/l1jump_jer_v1.json

per-|η| linear JER model for JUMP: σ(pT)[GeV] = eta.par0(ηbin)·pT + eta.par1(ηbin)

|η| boundaries at 1.3, 1.7, 2.5, 3.0 (defining 5 bins), arrays a and b

includes version and description metadata

Integration builds are failing. It seems they are not able to find the data. See for example here:

I think the issue might be explained at cms-sw/cmssw#48897 (comment)
