Tag Filtering Expressions

[SamStentz]

👓 What did you see?

tag filtering doesn't support nesting parentheses (more of a feature), nor does it implement commutativity of boolean algebra (why I made this a bug).

source code implementation

✅ What did you expect to see?

Parentheses and PEMDAS respect.

📦 Which tool/library version are you using?

v0.14.0

🔬 How could we reproduce it?

could use above example in newest release.

Steps to reproduce the behavior:

1. Install '...' version '...'
2. Create a file called '....'
3. Run command '....'
4. See error '....'

example test cases that I would hope for from the unit testing

var testcases = []testcase{
        ...
	{filter: "@ten, (@one && @two)", expected: []*pickle{p2, p3}}, // evaluate `,` second by setting parentheses, a feature
	{filter: "@three && @two, @one", expected: []*pickle{p1, p2, p3}}, // evaluate `,` and `&&` left to right, a bug (current behavior would be to only pass p3)
        ...
}

📚 Any additional context?

Hi Sam. If I understand correctly, you would like to able to have a feature that allows grouping of tag expressions? Basically have a more complete tag expression evaluator? Could you please provide some examples where this could be used? Thanks!
