Platform Ststm8 Versions Save

• Updated SDCC toolchain to v4.2.0 (#50)
• Added compatibility with PIO Core 6.0
• Improved support for bare assembly programming
• CONST area now taken into account when calculating flash memory usage (#54)

This release introduces initial support for debugging feature with a proper peripheral view. Many thanks to @cocus for the initial research, @maxgerhardt for a great implementation and @gicking for the SVD files. Due to several issues with SDCC and SPL/Arduino, debugging only works with bare-metal applications. Debugging of Arduino or SPL-based projects is not supported at the moment (see #44, #48).
