Expose iter

[pranav-bhatt]

Exposes the Iterator functionality of Attributes.

Fix #15

Check out the warnings (run cargo fix and then cargo fmt, so it fixes the imports)

Also, should the iterators implement ExactSizeIterator, since you know straight from the beginning how many attributes you have? If you need the code to calculate the number of attributes, i think you can find it in v1::EventFormatDeserializer

Would some values being None cause an issue while implementing ExactSizeIterator?

No because you calculate with a sum (like done in v1::EventFormatSerializer) the exact number of available attributes

small nit and we're ready to merge it!
