Postbuild Script applied to HIC MAX32625 release image not working Target: NRF52840

This is no longer a blocking issue for us. We have gotten by using our NRF52840-DK backup plan.
I still want to capture it because I'm sure we will meet again.

We were attempting to MSD flash a custom target based on NRF52840 using the MAX32625PICO https://os.mbed.com/platforms/MAX32625PICO/

We used the post build script on the MAX32625 release firmware (REL v0254)

@trowbridgec & I consistantly were finding the following two issues depending on how we ran the script

* unable to get the MSD to enumerate (@loverdeg-ep did see DAPv2 and webusb)
* MSD enumerates but after "flashing" reports failure due to inability to reset target

I did not try to debug with pyOCD nor did I try flashing via webusb.

I still need to gather some notes on the script parameters and results we were seeing.

Start with the postbuild script and its parameters for MAX32625 release firmware REL v0254, using the MAX32625PICO with the NRF52840 target. Review the reported MSD enumeration and target-reset failures, then compare results with pyOCD or webusb; done means the MSD enumerates and flashing completes without a reset failure.
