 Highlights:
 
 * Performance improvements:
-  - #1432: SERDES TTL inputs can now detect edges on pulses that are shorter
-    than the RTIO period
-  - Improved performance for kernel RPC involving list and array.

 * Coredevice SI to mu conversions now always return valid codes, or raise a `ValueError`.
 * Zotino now exposes `voltage_to_mu()`
 * `ad9910`: The maximum amplitude scale factor is now `0x3fff` (was `0x3ffe`
