Possible bug in get_process_info

[Andreas-Froyland]

One of the Dot X crashes had this heap corruption

dot_x!std::path::Path::to_path_buf
↓
dot_x!windows_volume_control::process_api::get_process_info
↓
dot_x!windows_volume_control::AudioController::GetAllProcessSessions

Things to check:
In windows_volume_control::process_api::get_process_info:

• manual CString::from_raw or String::from_utf16 without copying properly.

• unsafe FFI calls returning heap pointers that you free twice or free incorrectly.
