v0.3.0

New features:

• new command rm: delete a file on the Flipper
• synctime now calculates Flipper time skew just like qFlipper
• launch now lets you optionally specify arguments to the app you're launching

Changes/bugfixes:

• You can now use filenames of any length! This actually clarifies the code and the filename length checking before was probably inaccurate anyway
• ul (upload and launch) is no longer available. Chain together Flipwire runs (possibly with a sleep between as needed) to achieve the same effect
• Windows Bluetooth functionality is improved, with a scan method far more likely to work every time
• Update all dependencies and bring the project to Rust 1.76
