Update version to 0.3.0

This version adds support for a new syntax:

`iprintln!("a: 0x" a;X ", b: 0x" b;X);`

Unlike the older literal-based syntax, this new syntax allows for better
error reporting from the compiler and better syntax highlighting from
editors not explicitly made aware of this macro (which, to my knowledge
at the time of writing, is all of them).

Unfortunately, due to the nature of macros, editors may not be able to
refactor the contents of ifmt macro calls (e.g. CLion does not appear to
rename any identifiers referenced within user-defined macros when doing
identifier find/replace) and will not provide any error checking without
explicit support.

 To use ifmt in your project, add

 to your Cargo.toml.
 
 ## Examples
 ```rust
 let four = 4;
