Missing TICS Pro files used for ext clock progamming for ZCU111 (maybe other boards?)

[FredKellerman]

Some older designs rely on 245.76MHz would it be possible to add this setting to the list of supported external clock freqs?

The 245.76MHz TICS PRO settings file for the LMX part is missing from here:

https://github.com/Xilinx/PYNQ/tree/master/sdbuild/packages/xrfclk/package/xrfclk

The SD image for PYNQ v2.7 also matches and does not have this file, only the following are present:
