bc242390e7 Add packaging infrastructure 
Split up single script into a package with multiple modules.
Also add a setuptools control file. With this, stcgal can be
installed like any other program. It's still possible to launch
from the sources directly. stcgal.py has been converted into a
simple launcher.

v2: fix imports

d5b35cf43d Rename stc15 and stc15x protocols 
The protocol originally named "stc15" is only used for two early STC15
series, i.e. STC15F104/STC15F204. All other STC15 series appear to
use a different protocol. So switch around names similary to "stc12"
vs "stc12a".

In conclusion:
- "stc15a" is used only for STC15xx04E(A)
- "stc15" is used for all other currently tested STC15 MCUs

bf7cbb2042 Add support for new BSL 7.x STC15 parts 
These use a somewhat modified protocol with support for external clock.
This should get all STC/IAP15F2/L2 etc. work correctly. Only parts with
BSL 7.1 were tested, although BSL 7.2 should work as well.

The functionality is encapsulated in the new protocol "stc15x".

62c85d06c8 Add STC12A (early STC12) series protocol support 
STC12A is my name for the mixup protocol between STC89 and
STC12 that is used by some early STC12 series MCUs (for examples
STC12C2052AD). The protocol differs in many subtle ways so there is
quite a bit of unfortunate code duplication for the moment.

87a257e63e Improve synchronization and timeout handling 
Make sure we can safely sync to the status packet in case
garbage is received before.

407e956dfb Ignore garbage packets in synchronization state 
The MCU might still be running user code and toggling the UART pins
when stcgal is started. Just ignore all garbage we see in this stage
until we get a valid package.

b3230814a8 Erase flash in 512 byte blocks 
This is the IAP flash memory block size, and the BSL apparently
expects erase to be done aligned to 512 byte.

a82b0e4633 Handle UID with more flexibility 
Some BSLs only send the UID with the erase acknowledge packet,
others only send it with the program options acknowledge packet.
