Settings file needs to have a exclude / ignore mechanism

**There needs to be an "exclude" option e.g. "exclude .tests.ps1" **

I have a module with ~ 200 pester tests attached. In VSCode if I attach a settings file the analyzer reports each pester command in each file is not found, by default, in each of the profiles where pester is not present. This reports so many false positives it is impossible to see the things which should be fixed. (VS code just says "> 1000 problems" and stops counting!)

Proposed technical implementation details (optional)

An option in the settings file (and perhaps on the command line) which said "exclude files which match this regular expression" would allow a subfolder, or certain names to be ignored. This is preferable to scanning those files, and trying to figure out which messages to hide, or having a mechanism for saying "Tell me if I'm using a module which isn't in V6 ... except don't tell me about Pester ... unless I've used it outside this folder" .

What is the latest version of PSScriptAnalyzer at the point of writing
1.18.0

Start by tracing how PSScriptAnalyzer reads settings files and handles command-line options. Determine where file selection occurs and how an exclude pattern would fit both entry points. Done means users can exclude matching files so their diagnostics are not reported, including the Pester-related false positives described here.
