FITS type "bug" #77

Description

@phajy

Looking at some NuSTAR data it appears that one of the FITS files has an integer stored as a string. Here's the Stacktrace.

Stacktrace:
 [1] _read_fits_and_close(f::SpectralFitting.OGIP.var"#7#8"{Float64, Int64, Int64}, path::String)
   @ SpectralFitting.OGIP ~/Documents/GitHub/SWIFT_J0909/dev/SpectralFitting/src/datasets/ogip.jl:130

caused by: MethodError: no method matching Int64(::String)

I've called this as a "bug" but it is really just needing to handle a poorly typed FITS file.

Let me know if you need the specific code to reproduce this.
