Allow Bool values in cfg of in-memory run_omniscape?

[jessjaco]

The in memory version of run_omniscape has type Dict{String, String} for the cfg arg. Might it make sense to allow Bool values too, for e.g. calc_normalized_current?

It would be easy to update the dict type requirement Dict{String, Any} or Dict{String, Union{String, Bool}, but we'd have to make sure we're parsing things correctly. My original thought was that it's a bit easier to just enforce String as the value type for all keys so we always know what type to expect when parsing things.

Oh right, now I realize the numeric types are string too. Yeah, probably a low priority
