Update for 3.0.0

[AlejandroFuster]

This PR updates the tool to work with version 3.0.0 by adding the new version enum and updating all parser offsets accordingly:

• Bumped tool version to 1.7.5
• Added V300 enum variant
• Updated offsets for TurnipParser, VisitorParser, and DateParser (Weather seed offset remains unchanged from 2.0.x)

First off, thank you for creating and maintaining this amazing tool! It's been incredibly useful, and when the update to 3.0.0 came out, I genuinely missed being able to use it. The tool works so well that I couldn't go without it, so I took the time to update the offsets to make it compatible again

Looking forward to your feedback on these changes!

Closes #66

Thanks for your work, I tried updating the offsets but without a console to actually test on I apparently got them wrong.
Did you confirm that this work on hardware?

[AlejandroFuster]

Yes, I tested this on hardware! I verified the visitors and turnip prices, and both are displaying correctly with values that match. The weather seed also displays correctly. I confirmed this by restoring an old save and checking that it shows the same value, so the offset appears to be accurate.

Let me know if you'd like me to test anything else specific!

The weather seed offset matches what I had so it's probably correct. For some reason it looks like I messed up the turnip shop and visitor offsets. Thanks again for putting this together.
