New packets type definitions

[Lucashsmello]

See https://github.com/Lucashsmello/GIMX/wiki/Network-api-extended for details.

Notes:

• I assumed that float data type is always 4 bytes.
• struct s_network_packet_config is used to receive configuration settings as well as to send configuration settings.

Feel free to modify as you wish.

Hi, it has a really long time, but now i am back to do some modifications on GIMX.
Can you accept this pull request? This is necessary for matlo/GIMX#618.

Hi, what kind of application will use these messages? Except for the sensitivity, I find it tedious to directly change the values. This is the reason why the calibration mode exists.

For controlling GIMX through an android app or http (web browser). There is an example here https://gimx.fr/forum/viewtopic.php?f=11&t=2875&start=10. More details here: https://github.com/Lucashsmello/GIMX-WebAPI

Except for the sensitivity, I find it tedious to directly change the values. This is the reason why the calibration mode exists.

I can make the code for setting the calibration mode and changing calibration settings. As far as i know, there are three modes: normal mode, translation/acceleration/deadzone test calibration mode and circle test calibration mode.
What about something like this?

typedef struct PACKED
{
  uint8_t packet_type;
  uint8_t mode; // there are three modes: normal, translation_test, and circle_test
  float x;
  float y;
} s_network_packet_translation_test;

typedef struct PACKED
{
  uint8_t packet_type;
  uint8_t mode; // there are three modes: normal, translation_test, and circle_test
  float radius;
  float velocity;
  float ratio;
} s_network_packet_circle_test;
