Consider renaming package to adhere to julia package naming conventions

Specifically this rule linked in the developer guide:

Package Naming Guidelines

4. Err on the side of clarity, even if clarity seems long-winded to you.

RandomMatrices is a less ambiguous name than RndMat or RMT, even though the latter are shorter.

Sorry for jumping in with a nit-pick. It will take me some time to get up-to-speed with the project, just something that jumped out at me from the start.

Thanks @dgkf-roche, good point. @brockk not sure if we could do BayesSafetySignalDetect or something like that?

[brockk]

That's fine by me. I haven't submitted the abstract yet so can change it to whatever. Your suggestion is fine @danielinteractive

[brockk]

Maybe SafetySignalDetection.jl
?

The Bayesian bit is probably OK to drop.
