Compile error with just tzdb-concatenated

[ehuss]

The following generates an error when trying to build jiff 0.2.13

[dependencies]
jiff = { version = "0.2.13", default-features=false, features=["tzdb-concatenated"] }

Results in this error:

I don't know if it actually makes sense to have just that one feature enabled, but if not it might be nice to compile_error! with an explanation.

Nice catch. This should work. This particular feature combination wasn't being tested, but #367 fixes that (and the compilation error). Thank you!
