Processing of "symlinked" files

[caetera]

TRFP fails if the file to process is provided as a symlink if using Mono >6. See #108

• Check if the problem still exists
• Implement a (most likely) platform-dependent fix

Implemented in 82ff97c
Tested

• Ubuntu 20.04.5 LTS/Mono 6.12.0.182
• Windows 10.0.19044.2486/Native
• MacOS Ventura 13.2/Mono 6.12.0.188

Note
System security policy (to let terminal run unknown software) has to be changed on MacOS when processing symlinks
