regex 1.10 requires rust 1.65. So I've fixed it to 1.9.

This is a bit drastic and seems to cause problems with projects that don't fix regex. More specifically, probe-rs's renovate bot seems to be stuck because the bot previously updated regex to 1.10. Wouldn't a normal-ish regex = "1.9" have sufficed?

[burrbull]

Yeah. Looks like it was bad idea. We should just up MSRV.

this broke chiptool too. :)
