This PR makes four significant changes:

  1. Upgrades to PRBMath v4, which contains the fix for https://github.com/cantinasec/sablier/issues/2 and https://github.com/cantinasec/sablier/issues/1.
  2. Bumps all other submodules to their most recent versions.
  3. Increases the minimum Solidity pragma to v0.8.19, since this is a requirement of PRBMath V4.
  4. Adds a test to prove the monotonicity of the streamedAmountOf function (Write fuzz test that shows streamedAmountOf is a monotonic function #421)

@andreivladbrg, you can start reviewing this, though FYI I have also started working on #421, and I would like to include that test in this PR.

Update: I just pushed a commit to address #421 by adding a test that verifies the monotonicity of the streamedAmountOf function. The PR is ready to be merged now, subject to your review, @andreivladbrg.

I ran the monotonicity test on main, and it failed as expected:
