protecting buffering:
- ideally size the pvQueue so it is "bigger" than the dmaQueue.  then deadtime protects
  the pvQueue from overflow.
  o pvQueue is a low-rate queue, while dmaQueue is high-rate
- 2044 dma buffers +10% (204) for extra firmware buffers
- then we need (2044+204)/350 pvQueue buffers

Resetting Interpolating Encoder Data

Discussion on Oct. 4, 2023 with caf/claus/weaver/cpo

currently: configure launches worker, and the worker "remembers" by default
but Ric currently resets the worker memory on enable (which is good!)

should we "forget" old data under these conditions:
- new run?
- new step?
- enable?
- integrating detector pause? (hard)

propose:
- if it's not too hard,    "forget" on every enable (or disable) (fallback: beginstep/ends\
tep)
  o doesn't handle the integ-det-pause cause, but that's hard and
    we will make that clear to the scientists (eventual    solution may    be 1MHz    encoder)
- turns out ric already does this
