Add initial run of VC Spyglass Linting. Currently works by putting all results in lint-spyglass-reports dir which can be subsequently pulled up with spyglass. The scripts work in batch and can probably be tailored to ones liking in the lint_spyglass.sh bash script

# Author: james.stine@okstate.edu 11 June 2025

# Description:
|
||||
# This script automates the running of Synopsys SpyGlass linting for
|
||||
# various Wally RISC-V configurations. It substitutes the WALLYVER value
|
||||
# in the base project file and runs SpyGlass for a specified lint goal.
|
||||
#
|
||||
# - Cleans out the lint-synopsys directory (if it exists)
|
||||
# - Accepts one configurable linting goal
|
||||
# - Iterates over multiple Wally configurations
|
||||
# - Generates temporary .prj files for each run
