build: automatically install APSW

This is now available on PyPI #20

Have made sqlite-s3vfs depend on what is the most recent version of APSW. May
allow earlier versions down the line if we test them.

 ## Installation
 
-sqlite-s3vfs depends on [APSW](https://github.com/rogerbinns/apsw), which is not officially available on PyPI, but can be installed directly from GitHub.
+sqlite-s3vfs can be installed from PyPI using `pip`.
 
 ```bash
 pip install sqlite-s3vfs
-pip install https://github.com/rogerbinns/apsw/releases/download/3.36.0-r1/apsw-3.36.0-r1.zip --global-option=fetch --global-option=--version --global-option=3.36.0 --global-option=--sqlite --global-option=build --global-option=--enable-all-extensions
 ```
 
-Installing APSW from GitHub can be difficult on some platforms since it involves compiling a Python extension and (depending on options chosen) SQLite itself. As an alternative, sqlite-s3vfs should work with [apsw-wheels](https://pypi.org/project/apsw-wheels/), which includes binaries for various platforms.
-
-```bash
-pip install apsw-wheels
-```
-
-However, at the time of writing aspw-wheels has no official relationship with APSW.
+This will automatically install [boto3](https://boto3.amazonaws.com/v1/documentation/api/latest/index.html), [APSW](https://rogerbinns.github.io/apsw/), and any of their dependencies.
