Feature: add fuzzing parameters

[drgorillamd]

Add a way to support variables which should be fuzzed

This could be:

• have new keywords parsed in the .tree (between, greater than, lesser than, equals for the opposite/reverting)
• add arguments to the function signature, based on these
• create a range for this values (using forge-std bound)

For instance

Test.Test
├── When X is between a and b 
└──── it should do something

should then have a corresponding test

function test_WhenXIsBetweenAAndB(uint256 fuzzedX) external {
    fuzzedX = bound(fuzzedX, A, B);
    // It should do something
