Dustin Oprea 74a1612f20 v3/ifd_enumerate: Skip tags that have a divergent embedded type 
This should mitigate most issues where the same tag appears multiple
times with different types. This happens more than you would think that
it would.

- ErrTagTypeNotValid is now returned unwrapped.
  - This is typically the convention for static error messages.

waiting on v3 to be forked.

Dustin Oprea 312218d7b1 Use encapsulated data/reader rather than bytes 
Given a stream of data, it is possible to determine the beginning of
EXIF data but not the end. Therefore, either an image-aware
implementation must know how to parse an image and extract the EXIF
data or a brute-force search implementation (one of which is provided
by this project) must find the start anchor and then return all bytes
from that to the end of the file.

We have been made aware of some use-cases where a brute-force search
might be unavoidable due to trust or stability issues with the image
structure. This leads to large allocations. This can be avoided by
accomodating support that will allow for both a byte-slice or an
`io.ReadSeeker`. Since the EXIF structure is typically not read-
intensive (a couple of kilobytes if no thumbnail is present), this
should have a minimal performance impact.

Closes #42
