nirfsg 1.0.1

• Changed
  • Added default value for module parameter in get_self_cal_last_date_and_time and get_self_calibration_temperature methods to align with documentation and allow duck-typing
  • Changed the parameter name for waveform name from name to waveform_name in clear_arb_waveform and select_arb_waveform to be consistent with other waveform methods
  • Changed the name of below methods to be consistent with other APIs in the repository
    • get_self_calibration_last_date_and_time to get_self_cal_last_date_and_time
    • get_external_calibration_last_date_and_time to get_ext_cal_last_date_and_time
  • Changed frequency_settling property to be of type float instead of hightime.timedelta, since it can have multiple interpretation based on frequency_settling_units property value
  • Changed interpolation_delay and relative_delay properties to be of type hightime.timedelta, so that it aligns with delay attributes across other APIs in the repository
  • Changed exported_ref_clock_rate and ref_clock_rate properties to be of type float instead of enum, since the enums just represented raw float values
  • Fixed the return type of get_all_script_names and get_all_named_waveform_names to remove the size parameter and return a list of strings instead of a comma-separated string
  • Updated external_calibration_recommended_interval property to return a hightime.timedelta object instead of months as an int, aligning with other APIs in the repository
  • Updated self_test to not have any parameters, aligning with other APIs in the repository
  • Updated wait_until_settled method to have max_time_milliseconds parameter as type hightime.timedelta with a default value of 10 seconds
  • Updated below properties and method parameters to be of string enum type instead of plain string, since they would support only fixed set of strings
    • pulse_modulation_source
    • exported_pulse_modulation_event_output_terminal
    • exported_ref_clock_output_terminal
    • lo_source
    • arb_sample_clock_source

Fake Release to Fix Internal Testing

This is not a real release.
Our internal tests for nimi-python were failing the system tests due to a driver change.
This required an update to the system tests and a new release tag so that we would copy the latest version of the tests for our internal testing.
