Dependency compatibility bounds are too loose

[jishnub]

At present the compat entries are https://github.com/JuliaAstro/FITSIO.jl/blob/a9a14fba3919d8f0ad8d0f64c9a59679d51ff98e/Project.toml#L11-L12

Perhaps we should shift to the caret bounds from the inequalities? In any case the julia registry places an upper bound on the julia version, but apparently it doesn't on the other dependencies.

You are correct and pull requests are always welcome :wink:

Thanks, I'll submit a PR soon that addresses this and #129.
