Good day, [~mgrigorov] !

Before I make a PR with my ideas, I'd like to discuss the ways you see it best for avro.

Would you please answer, if such a things might be good to be resolvable to decimals:

1) Float/Double;

2) String representation of floating-points numbers;

3) Array of integers as bytes.

Confirm, if project is interested in such features, then I'll implement them.

> Firstly, I have a question - maybe I've missed something - how to properly resolve json-based avro data with decimal avro schema(either based on bytes or fixed types)?
> I think it's impossible to resolve json-based avro data with decimal schema - I've tried some variants, like passing bytes as Unicode symbols, or passing array of bytes directly, or even simply float numbers - nothing works.
> My proposition is to allow decimal resolving on following json variants:
> 1) Array of u8;
> 2) float value;
> 3) integer value.
> String is kinda dangerous to allow resolving, as it might be malformed.
