AutoCounter enables the addition of ad-hoc counters using the ``PerfCounter``
object in the `midas.targetutils` package. PerfCounters counters can be added in one of two modes:
# `Accumulate`, using the standard ``PerfCounter.apply`` method. Here the annotated UInt (1 or
more bits) is added to a 64b accumulation register: the target is treated as
representing an N-bit UInt and will increment the counter by a value between [0, 2^n - 1] per cycle.
# `Identity`, using the ``PerfCounter.identity`` method. Here the annotated UInt is sampled directly. This can be used
to annotate a sample with values are not accumulator-like (e.g., a PC),
and permits the user to define more complex instrumentation logic in the target itself.
