feat: 0.1.6-rc.1 Bump dependencies

[jgabaut]

Changed

• Drop app::controller::{write_temp_style_file, load_style_from_memory}
  • Use raylib::prelude::RaylibGuiState::gui_load_style_from_memory
• Bump raylib to 6.0.0-rc.2
  • WIP: currently, build fails for mingw-w64, I tried unstableto have the bindgenpatch in chore: bump bindgen to 0.72.1 raylib-rs/raylib-rs#321 to rule out Missing fields in nested class with LLVM 22 rust-lang/rust-bindgen#3264 but it was not the solution.
• Bump pdf-writer to 0.15.0
• Drop uuid dep

References:

• Possibly raylib 6.0.0-rc.2 not setting target explicitly:
  • [FEATURE] Set target explicitly in bindings generation raylib-rs/raylib-rs#324
  • WIP: try setting bindgen target explicitly for X-windows-gnu targets raylib-rs/raylib-rs#325
• Handwavy bindgen chicanery:
  • Bindgen >=0.58 produces an invalid union with both packed and align representation hints  rust-lang/rust-bindgen#2159
  • clang_macro_fallback doesn't propagate implicit --target to fallback translation unit rust-lang/rust-bindgen#3352
  • fix: support header_contents() with clang_macro_fallback rust-lang/rust-bindgen#3353
  • [BUG] Invalid binding generation resurfacing after 0.70 rust-lang/rust-bindgen#3381

Merging this would fix CI:

• chore: opaque type __mingw_ldbl_type_t raylib-rs/raylib-rs#322
