Changes:
dcf77pi:
- Calculate century (modulo 400) from year, month, day of week, day of month
- New parameter -S to set the system time
- Improvements to DST handling
- Set error state if day of month is too large, not just when greater than 31
readpin:
- New parameter -t for readpin to adjust nanosleep() delay
- Determine realfreq dynamically, do not use realfreq from config.txt
general:
- Documentation updates
- Code cleanups
- New algorithm to receive bits from the radio signal from an idea by
Udo Klein, with permission [1] (configuration file changed)
- Use two independent maximum values for 0 and 1 bits (configuration
file changed)
- New verbose display output
- Weaken precondition for processing leap seconds and DST changes to not
insist on correct values for parity bits and bit 0, 20, 17, 18
- README.md updated
- Style and other minor fixes
* Simplify PORTDOCS installation

- better detection for bits in the radio signal
- catch more corner cases in decoding of the time data
The configuration file (hardware.txt) needs to be updated with this update.
platform but might work on other devices using GPIO pins too.
The received data can be logged for later playback/analysis.
