Esp32ExceptionDecoder: decode stack overflow backtraces

[jarkad]

This PR makes esp32_exception_decoder match lines similar to:

***ERROR*** A stack overflow in task main has been detected.


Backtrace: 0x40081d06:0x3ffcca50 0x4008554d:0x3ffcca70 0x4008846e:0x3ffcca90 0x4008711f:0x3ffccb10 0x40085648:0x3ffccb30 0x400855fa:0x00000017 |<-CORRUPTED




ELF file SHA256: 91d3d8aaa6b7beec

CPU halted.

Note the |<-CORRUPTED part that the old regex doesn't match.
