Adding Assembly Support

[Navonil Das]

In Our Current System, we only support the sketch file(ino) compilation. We need to add support for compiling assembly language.

Changes Required:

1. Modify tasks.py.
2. Add a new route for compiling Assembly.
3. Update api.service.ts.
4. Modify the CompileCode Functions inside Workspace.ts.

Compilation Command:
avr-gcc -xassembler-with-cpp file.s -mmcu=atmega328p -nostdlib
