2d3c24fc3a Timing improvements 
* Reduce delays from 200 ms to 100 ms, since 200 ms tends to be too long
  overall.
* Increase pulse interval to 30 ms to avoid the chance of stray pulses
  after MCU starts sending info packet.
* Add 30 ms delay after autoreset cycle to avoid glitches on startup

761c68e469 frontend: fix disconnect when autodetection fails 
We don't know the protocol version so we can't actually disconnect,
just skip it.

187aa9a3cf stc15: erase EEPROM flash when needed 
If option eeprom_erase_enabled is False, we need to signal to the BSL
to explicitly erase EEPROM flash when needed.

Addresses #59.

3cf2cb38e7 stc15: reduce sleep after baudrate switch 
We just sleep 200 ms, but apparently that's already too much with some
handshake baudrates. Cut it in half to fix
failures with "-l 9600" in some cases.

Addresses #17.

df2fbc23cd stc15: fix baudrate switching 
Baudrate switching fixes for both HW and SW UART devices:

* Program secondary SW UART timing parameter correctly. Supposedly this
  controls the sampling position when receiving data.
* Swap around trim range/adjust parameter for HW UART devices (as
  determind by older traces)
* Use correct constant for timing calculations

This should fix some STC15x10xW series MCUs. Compatibility to other
devices might be improved as well.

Addresses #17.

c5d509d1fa Add "stc89a" protocol 
This protocol variant is designed for newer STC89 series chips with BSL
version 7.x.x. The new firmware uses framing
with 16-bit checksum.

This protocol variant is currently untested because I don't have any
hardware at hand.

Addresses #50, #40.

6b83017de9 Raise minimal Python version to 3.5

Python 3.4 is EOL for some time and even 3.5 reached EOL recently. So
just switch to that as minimum version.

CI: try to fix and simplify apt setup 
Run apt update to update the package cache, as this seems to be needed by
Travis now. Also reduce the package set - we don't build any deb or rpm
packages anymore. This should hopefully fix the CI build.
