v0.2.0

Added

• implicit property to TrackedReferences - these don't show up in diagrams
  or equation lists, but are still calculated during simulation/bayesian
  inference
• ExtendedOperation base class, this is an Operation that's built with
  internal implicit components
• pulse, repeated_pulse, step operations
• delay1, delay3, smooth extended operations
• Explicit dtype and shape properties to EquationPart
• An additional data dimension through the dim attribute on
  TrackedReferences, allowing the value at each timestep to be a vector rather
  than a single value
• A plot_refs_single_axis visualization function that will graph all
  references on the same set of axes each with their own ranges
• Ability for distributions to generate per timestep rather than singular static
  values or vectors

Changed

• All eval functions now default to t=0 if unspecified (allows non-time-based
  equations to run a bit more ergonomically)
• Moved PostMeasurement implementation to base Metric class, as it's the
  most basic/obvious type of metric to use
• Aggregate operations to operate in the data dimension by default, the new
  timeseries property/operation on tracked references can be used to apply
  aggregate operations (e.g. within metrics) across the time dimension

Fixed

• Model's .pymc function not correctly using the passed number of timesteps
• Reference values incorrectly being converted to floats when didn't start off
  as floats

Removed

• Support for python 3.10 (exception add_note() functionality is only in >=3.11)
