Make the bindings/cpp CMake project installable (#416)

Browse Source 
This leverages the still-undocumented `corrosion_install` to get
an installable ffi binding that can be consumed by other projects,
e.g. from yocto:

```
$ ninja install
[4/5] Install the project...
-- Install configuration: "Debug"
-- Up-to-date: /home/milian/projects/compiled/regorus-test/lib/libregorus_ffi.so
-- Up-to-date: /home/milian/projects/compiled/regorus-test/include/regorus_ffi/regorus.hpp
-- Up-to-date: /home/milian/projects/compiled/regorus-test/include/regorus_ffi/regorus.ffi.hpp
-- Up-to-date: /home/milian/projects/compiled/regorus-test/lib/cmake/regorus_ffi/regorus_ffi_targets.cmake
-- Up-to-date: /home/milian/projects/compiled/regorus-test/lib/cmake/regorus_ffi/regorus_ffiConfig.cmake
-- Up-to-date: /home/milian/projects/compiled/regorus-test/lib/cmake/regorus_ffi/regorus_ffiCorrosion.cmake
```

This can then be consumed as such:

```
find_package(regorus_ffi CONFIG REQUIRED)

add_executable(test test.cpp)
target_link_libraries(test PRIVATE regorus_ffi::regorus_ffi)
```
