CE C/C++ Toolchain (v14.0)

The v14.0 toolchain adds many functions, fixes bugs, and applies optimizations here and there.
Merry Christmas! 🎄

This release is brought to you in particular thanks to @ZERICO2005 who did almost all of the work!

Highlights:

• Massive expansion of libc functionality: strto*, atoi/atol/atoll, strlcat, memmem, memrmem, strrstr, stpncpy, strspn/strcspn/strpbrk, etc., many implemented/optimized in handwritten assembly.
• Added sscanf and vsscanf
• Wide-character and C95 additions: wint_t, <wctype.h>, <cfenv>, numerous wmem* and wcs* helpers.
• C++ library updates: added <complex>, improvements to <type_traits>, fixes to C++98 headers.
• Math and floating-point: new/optimized dtof, (u)lltod, logbf, ldexpf behavior fixes, and scalbln(f/l).
• IO and tooling fixes: fclose correctness, stdio.h cleanup/rename helpers, fileioc performance and docs, gfx_AllocSprite bug fix.

CE C/C++ Toolchain (11.0)

The v11.0 toolchain includes support for working with USB devices! 🎉

Thanks to the hard work by @jacobly0, a new CE library named usbdrvce is available for interfacing with the USB port of the calculator in either host or device mode. Additionally, @commandblockguy has created the srldrvce library for communicating with USB serial-based protocols such as CDC and FTDI. For mass storage devices such as flash drives and SD cards, @mateoconlechuga implemented msddrvce and fatdrvce for reading and writing logical blocks on the drives, as well as providing functions for interacting with a FAT32-based filesystem.

These libraries took a long time to get to this point, and still are being worked on, so give them a try and report any issues you may encounter. Join our Discord/IRC chat in order to ask questions, or provide input on what you would like to see in terms of documentation for interfacing with these libraries.

Thanks to all the contributors!
