dd259b4957 Make deepMatch report in linear time 
The current implementation of the deepMatch() has the exponential runtime.
Given the long enough input and the pattern with multiple wildcards
it takes a while if ever to complete which can potentially be used
maliciously to cause a denial of service (cpu and memory consumption).

E.g. running this in the root of this repository
time yq eval '.jobs.publishDocker.steps.[] | select (.run == "****outputs")' .github/workflows/release.yml
gives on my laptop
25.11s user 0.06s system 99% cpu 25.182 total

Whereas the updated implementation gives
0.01s user 0.01s system 36% cpu 0.049 total

There are numerous similar CVEs reported for glob evaluation in
different shells/ftp-servers/libraries.

The replacement implementation with the linear runtime is shamelessly taken
verbatim from the briliant article by Russ Cox https://research.swtch.com/glob
