v1.1.1

• Fixed parameter description for minimum length. It now correctly reads that increasing this parameter reduces tracking noise.
• Rarely used but heavy packages like opencv, scikit-image, and scikit-learn are no longer loaded eagerly with import lumicks.pylake. Rather, they are loaded on-demand the first time that a feature needs them. This makes importing pylake itself faster and mitigates potential third-party issues (e.g. this makes the first issue from the F.A.Q. less severe as it no longer affects all users).
