fix(common.encoding): Remove locally-defined errors and use upstream ones

[Snelius30]

Summary

We have a local defined error (ie ErrShortDst, ErrShortSrc) objects in decoder_reader.go which has transferred from an original transformer package. Those uses inside the Read() function to properly manage a slice allocations. It does not work
cause errors.Is never set to true cause local errors object it's not the same transformer defined errors objects.
I got this error on my production when character_encoding = "utf8" option was used for inputs.file and dst buffer size is not enough to decode obviously.
Well, we need just to use a proper error objects. This PR to solve the problem. Thx.
