csharpier does not respect editorconfig specific c# rules

Issue

Csharpier fails to adhere to the specified guidelines for .cs files.

.editorconfig

root = true

[*]
charset = utf-8
tab_width = 2
indent_size = 2
indent_style = space
insert_final_newline = true
trim_trailing_whitespace = true
max_line_length = 200

[*.{cs}]
indent_size = 4
tab_width = 4

Bonus: We do use [*.{cs,csx}] and [*.{cs}] sometimes. It would be nice if the "more specific" rule takes precedence. eg [.{cs}] is used ultimately for formatting.
But probably an override mechanism is necessary: base editor config rules + override with [*.{cs,csx}] + override with [*.{cs}], which results in formatting with indent_size = 4

Example:

[*]
charset = utf-8
tab_width = 2
indent_size = 2

[*.{cs,csx}]
indent_size = 3
tab_width = 3

[*.{cs}]
indent_size = 4
tab_width = 4

This example results in formatting with indent_size = 4

Input:

namespace X;

public class Resolver
{
    private const int SinglePhase = 1;

    public int Resolve(object source)
    {
        if (source is not string)
        {
            return default;
        }

        return 0;
    }
}

Output:

namespace X;

public class Resolver
{
  private const int SinglePhase = 1;

  public int Resolve(object source)
  {
    if (source is not string)
    {
      return default;
    }

    return 0;
  }
}

Expected behavior:

Csharpier does not change Input. Formatting Input results in Input

I've narrowed this down to CSharpier not working with braces in the glob, which means a pattern like this will not work [*.{cs}], but [*.cs] does.

For this example

[*]
charset = utf-8
tab_width = 2
indent_size = 2

[*.{cs,csx}]
indent_size = 3
tab_width = 3

[*.{cs}]
indent_size = 4
tab_width = 4

According to the editorconfig spec, the most recent rule is what should be used. Which would result in an indent size of 4.

Which means for this example, indent size of 3 should be used for *.cs files even though the last rule isn't as specific. I imagine trying to code for most specific rule would be problematic.

[*]
charset = utf-8
tab_width = 2
indent_size = 2

[*.{cs}]
indent_size = 4
tab_width = 4

[*.{cs,csx}]
indent_size = 3
tab_width = 3

I agree sticking to the editorconfig specification is the way to go
