[feature] Include modelsim's vsim for linter

[ungultig1]

Hello @suoto ,

by any chance, are you looking forward to include "vsim" to your linter-functionality?
As i can see inside the source code (msim.py) you first create the library by invoking vlib and vmap, following vcom-compilation for vhdl-files.
As vsim delivers additional vhdl-error-checks (especially for generic maps), I wonder, if you could finish the linter'ing with vsim after vcom.

As I am aware, the vsim-command, which should be invoked for every file in project is the following (inside the HDL_CHECKER_WORK_PATH):

vsim default_library.exampleVhd -c -do "run -all; quit"

Thank you. Greetings.
