I've been fighting with this across multiple versions of lldb. I'm trying to print a `uint8_t[32]` as an array of unsigned integers, but it keeps printing as a binary string. What follows is all the different ways I tried manually setting the format manually to `dwim-print`, and using `type format add`. Regardless of what I do, the variable is always formatted as a binary string.

LLDB versions tested:
* lldb version 20.1.3
* lldb-1600.0.39.10 (Apple clang)
Anyone got a suggestion how to just print it as an array of integer values?
