Implement test matching pattern in hivesim-rs

[ogenev]

Running and matching on a specific portal hive test helps us with local development and debugging.

Example implementation in GO: https://github.com/ethereum/portal-hive/blob/main/hivesim/testmatch.go

We want a functionality to match a test to a regex pattern. The idea is to use hive
--sim.limit <pattern> cli to specify a regular expression to selectively enable suites and test cases. This is interpreted by simulators and it sets the HIVE_TEST_PATTERN environment variable.

Right now, hivesim-rs don't use this functionality because a test matcher is not implemented.

hi @ogenev, I didn't realise that this is not a ticket for the go implementation
I haven't worked with rust before so wouldn't be able to contribute to this

if anyone else can assist with the issue, kindly do so
thanks
