added spicinit web arg option to hiedr2mosaic.py

[Hyradus]

I have edited spice function to accept a new variable web and changed also the spiceinit command to accept this variable. The variable web is linked to a new argument -w (--web) which enables the usage of spiceinit web kernels. Default is disabled.

Motivation and Context

As per described in 389:

Due to recent changes in ISISDATA structure, I cannot process anymore hiedr2mosaic.py since it crash at spice function due to missing kernels. Running the hiedr2mosaic.py commands one by one, highlight exactly the probelm with spiceinit since if I use spiceinit WEB=True, it works flawlessly.

How Has This Been Tested?

Tested on few HiRISE EDR images.
