[BUG] Option to execute xvlog at file location

[andreiGeorgian]

Describe the bug

The use case is for SystemVerilog classes and packages. Let P be the main package (./pkg.sv):

• P includes the next files (classes): ./transaction/c0.sv, ./transaction/c1.sv, ..... ./transaction/c15.sv
• if the class files also include some file from upper directory (../ , being the same dir that contains pkg.sv), then xvlog will create an internal path that is very long: ./transaction/../transaction/../transaction/../transaction/../transaction.......

The only solution that I found is to run xvlog from the same directory as the file being opened. This feature is already implemented for verilator linter. I went to extension man.js file, got the code from verilator implementation and used it to xvlog. Now is working Ok.
Can we have this option in the feature?
