feat: support Firfox profiles

See here for official documentation on Firefox profiles management.

Hi,
Thanks for your contribution.

A few points:

1. Please add the extra dependency to the setup file so it would include the dll file:
   https://github.com/zumoshi/BrowserSelect/blob/master/BrowserSelect/installer.nsi#L40

2. As I mentioned in the comment, you need to also commit the csproj file

3. I get 2 firefoxes on a default installation before creating any profiles
   
   Perhaps you have to remove one like I did for chrome?

4. I'm not very familiar with how firefox profiles work so I may be doing something wrong but the app seems to lag behind one profile? (as in I create the profile, browserselect won't pick it up, I create another profile, it picks up the previous one)
   
   
   I did run firefox with the new profile before clicking on refresh browsers from settings.

There are also some unlabeled firefox icons (without any profile name)

5. If there are two firefox instances (of different profiles) open, trying to open a link in one of them just opens a new firefox window with no link

This feature was brought up in #14 but I didn't find any way to communicate with open instances to open a new tab in a specific profile which is why this wasn't implemented.

Which command-line flags are you using to open the link in a new tab of a running instance of a certain profile in firefox?

Please also include changes to the .csproj file, specifically this addition:

<Reference Include="INIFileParser, Version=2.5.2.0, Culture=neutral, PublicKeyToken=79af7b307b65cf3c, processorArchitecture=MSIL">
      <HintPath>..\packages\ini-parser.2.5.2\lib\net20\INIFileParser.dll</HintPath>
    </Reference>

Otherwise it won't compile

Running a few more tests it seems firefox now correctly handles -p profile link. Interesting, It didn't do that before.
We need to do some tests to detect which version has introduced this change and either auto-detect it or provide an option in case someone is still using a pre-Quantum firefox version.

The weird behavior of opening a new window without a link seems to have something to do with how Program.Args2Str escapes the arguments:

That still doesn't explain the missing profile names though.
But since there is now support in firefox for this I will merge it as soon as the issues are resolved.

I'll try resolving these issue later. It seems that there are some problems on Firefox handling link in specified profile.

This seems to work consistently for me:
firefox.exe -P default -new-tab "http://www.example.com"
See:
https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options#-new-tab_url

This option seems to have been around for a while now (seems to have worked back in Jan 2020) for this user;

Adding the new-tab parameter may ensure better (backward) support??
