v2.0.0

This release simplifies applying functions to time series:

• Before: some_function(data.times, data.my.series, *args)
• After: data.my.series.some_function(*args)

This makes it easier to e.g. plot a series and its derivative:

fox.plot(
     data.observation.servo.left_wheel.torque,
     right=data.observation.servo.left_wheel.torque.low_pass_filter(T=0.05),
)

Added

• Add a Fox.empty() method to start from an empty state
• CLI: List available functions in the initial prompt
• Internal: Add reference to time values in each series instance
• Series: divisions between series and scalar values
• Series: products between series and scalar values
• Series: unitary minus operator
• Top-level decode function to unpack dictionaries from files

Changed

• Breaking: Function: absolute value moved to Series
• Breaking: Function: low-pass filter moved to Series
• Breaking: Function: standard deviation moved to Series
• Breaking: Function: time-derivative by finite differences moved to Series
• Breaking: Rename FoxplotException to FoxplotError
• Breaking: Rename Series to LabeledSeries
• Breaking: Rename the front class FrozenSeries to Series
• CICD: Update checkout action to v4
• Default constructor of Fox now requires a file name or path
• Update to latest uplot-python API

Fixed

• Correct some type annotations
• Make sure time values are scalar timestamps
• Use correct timestamped uPlot argument

Removed

• Breaking: Remove Fox.freeze function
• Breaking: Remove Fox.labels property
• Breaking: Remove Fox.read_from_file function (moved to constructor)
• Breaking: Remove left_axis_unit argument of plot function
• Breaking: Remove right_axis_unit argument of plot function
• Clean up unused internal color picker
