Suppress exif_read_data() errors

[avataru]

exif_read_data() can sometimes generate errors and should be suppressed. The same suggestion is made in a comment to the SE post that served as inspiration for the imageCreateJpegfromExif() method.

It's already implemented in library. Are you using latest version?

@adityapatadia I think your misunderstanding @avataru, he is talking about php errors that one can not catch, but is just outputed directly. Thats why it should be supressed in this library, as you later checks if the data was retrieved. I opened #93

@adityapatadia Thanks for merging #93, could you please release a patch version to include the fixes?

[avataru]

Thank you @hultberg and @adityapatadia
