Updated streaming scripts. Compiler compatibility for _delay_ms().

- Moved obsolete streaming scripts to folder for reference.

- Added a more complex Python streaming script which uses the serial
buffer as an additional streaming buffer.

- Removed all references to a _delay_ms(variable) to allow for better
porting across different compilers.
