UCVM cvmsi tapering for CyberShake Study 22.12

UCVM tapering
interp Zrange is set to [0,700] initially
related ucvm_query flags that affects tapering:
-L vs,vp,density (optional)
example, -L 200,-1,-1
(only floor the vs to 200)
-m cvmsi,elygtl:taper
(adding tapering interp to cvmsi)
-z zmin,zmax (optional)
(zrange values, original default: zmin = 0, zmax = 350)
UCVM's implementation of ucvm-tapering is ..
zmax fixed at 700
outside of zrange
below zmin, process GTL (vs30 to vs)
above zmax, straight CRUST pass thru
inside of range
calculate target-taper values
*** THIS IS NEW ***
Added an additional backend query
to get the original interp_crust value
and brought it back from backend to use for this
--- only implemented for plugin modules
*** What does this mean?
unless the non-plugin module set these values,
tapering is not going to work. ie. cvmh
can not be tapered, (not sure if it makes sense)
but cvmhlabn could be tapered.
if interp_crust.vs < target-taper.vs
use interp_crust
else
use target-taper
default vs_floor 500, vp_floor 1700, density_floor 1700
if there is a user-defined floor from ucvm_query command line option, use user-defined floors
orig_ratio= vp/vs
Rule 1,
if vs < vs_floor:
vs=vs_floor
vp=vs_floor * orig_ratio
Rule 2,
if vp < vp_floor:
vp=vp_floor
Rule 3,
if density < density_floor:
density=density_floor
Rule 4,
if (vp/vs) < 1.45:
vs=vp/1.45

Plot the binary file
To plot these files with ucvm_plotting, data ingest mode of plot_z10_map.py and plot_z25_map.py from ucvm_plotting is used but first needs to change those file name to have .binary file name so plotting scripts know how to parse the data
