Security patches are only available for the last 5 minor branches, so
since we're bumping pretty much everything right now anyway, let's bump
this number as well.
There is definitely syntax in this library now that's newer than 1.0
anyway (`with` was introduced in 1.2, for instance).
Restructuring: Isn.Extension is now called Isn, which means that the postgrex
configuration line becomes a bit shorter now:
```elixir
{:ok, pid} = Postgrex.Connection.start_link(
database: "isn_test",
extensions: [{Isn, {}}])
```
instead of the previous version, with `extensions: [{Isn.Extension, {}}]`.
I also implement the entire library in the `lib/isn.ex` file, since it felt
pretty silly to have eight different one-line files under `lib/isn/` looking
like this: `defmodule Isn.ISBN, do: use(Isn.Base, :isbn)`
We now have the following types:
- ISBN
- ISBN13
- ISMN
- ISMN13
- ISSN
- ISSN13
- EAN13
- UPC
