## Summary
Adds a unified mechanism for locating third-party IO DLLs through environment
variables, on top of the existing per-game `[xxxio] path=` INI setting.
## Changes
For each IO DLL, the path is resolved in this order:
1. The section-specific INI value, e.g. `[mai2io] path=`.
2. The section-specific environment variable, e.g. `SEGATOOLS_MAI2IO_PATH`.
3. `SEGATOOLS_IO_ROOT` joined with the default IO DLL filename, e.g.
`%SEGATOOLS_IO_ROOT%\mai2io.dll`.
4. Empty path, which keeps the built-in IO implementation (unchanged default).
INI and environment-variable paths are run through Windows environment-variable
expansion, so values such as `%SEGATOOLS_IO_ROOT%\mai2io.dll` are valid in the
INI directly.

- Configure separate pedals which are not part of the steering wheel (base)
- It is now possible to have a different steering wheel, pedal and shifter brand all connected to 3 different USB ports
- XInput does not have a deadzone at the end of the max steering anymore and the `restrict` setting works as intended
Optional for now, since not all games or configurations may need it.
It may be better eventually to refactor hooklib/path.c to allow for
static path remapping, to minimize boilerplate code around the functions.
The default value being commented out is no doubt a great source
of confusion whenever somebody attempts to edit it without
realizing that it is a comment.
