Add more validation of the /Filter entry, in image dictionaries, to the PDFImage constructor

Browse source 
Given that the code is currently assuming that the /Filter entry is a `Name`, it cannot hurt to actually ensure that's the case.

Also fixes an error message, for JPEG 2000 images with unsupported ColorSpaces, since `this.numComps` hasn't been initialized when it's accessed during the `throw new Error()` invocation.
