Go Imagick Files

New in minor release v3.7.0

Breaking API changes - [#319] GetImageBlob and GetImagesBlob signatures have been updated to return an error as the second element. This is needed to correct a fault in the original implementation which was masking and clearing errors, making it hard to debug, as a user. In an effort to be more idiomatic, it was better to adjust the signature and guarantee to the user that we will return a related error instead of expecting them to check the byte slice for nil and then call GetLastError - [#139] Move SetResourceLimit from being a method of MagickWand to a package function, as it has nothing to do with the wand instance

Other change

• [#317] Add GetDelegates and GetFeatures package functions
• [#320] Add MagickWand.GetImageProfileBytes method to return original bytes instead of converting to a string
