2.6.4

Added:

• Add the "thorpluto" tool for writing data from the ADALM PLUTO using GNU Radio. This script requires gr-iio to run. Note that this script duplicates some of the functionality of the existing "thor" recorder script, and may be subsumed or arguments may change in a future consolidation.
• Option to use the CMake variable Python_EXECUTABLE to manually set the path to the Python interpreter (useful if autodetection fails or Python 2 is preferred).
• Add stop_on_time_tag parameter to the Digital RF Sink blocks, useful when time tags only happen for USRP dropped samples but the 'rx_time' tag value falsely indicates no drop.
• Add the "thorosmo" tool for writing data from osmosdr-supported receivers using GNU Radio, and add the "uhdtodrf" tool for writing data from UHD devices using the UHD Python API without using GNU Radio. Note that these scripts duplicate some of the functionality of the existing "thor" recorder script, and they may be subsumed or their arguments may change in a future consolidation.
• Add option to force polling for watchdog functions (ringbuffer, mirror, etc.), which is useful as a fallback when the default watchdog observer fails silently.

Changed:

• The thor.py script's stop_on_dropped parameter now includes the new stop_on_time_tag behavior.

Fixed:

• Fix an IndexError when using stop_on_skipped or stop_on_time_tag with gr_digital_rf.digital_rf_channel_sink. If the skip/tag happened with only one data block to be written, the IndexError would trigger upon trying to index to a second data block.
