Add functions for mutating the CAN/CANFD Structs to C API

[tt-MarkSchadow]

It is currently not possible to set the timing parameters or the iso compliance using the C-API.
So I propose to add the functions as follows:

icsneoc.h

/**
 * \brief Get a mutable CAN_SETTINGS struct for the specified device
 * \param[in] device A pointer to the neodevice_t structure specifying the device to operate on.
 * \param[in] netid The network for which the baudrate should be retrieved.
 * \param[out] can_settings_struct Address to a pointer that will hold a reference to the struct
 * \returns True if the struct could be retrieved
 *
 */
extern bool DLLExport icsneo_getMutableCANSettingsFor(const neodevice_t* device, neonetid_t netid, CAN_SETTINGS** can_settings_struct);

/**
 * \brief Get a mutable CANFD_SETTINGS struct for the specified device
 * \param[in] device A pointer to the neodevice_t structure specifying the device to operate on.
 * \param[in] netid The network for which the baudrate should be retrieved.
 * \param[out] canfd_settings_struct Address to a pointer that will hold a reference to the struct
 * \returns True if the struct could be retrieved
 *
 */
extern bool DLLExport icsneo_getMutableCANFDSettingsFor(const neodevice_t* device, neonetid_t netid, CANFD_SETTINGS** canfd_settings_struct);

icsneoc.cpp

bool icsneo_getMutableCANSettingsFor(const neodevice_t* device, neonetid_t netid, CAN_SETTINGS** can_settings_struct) {
	if(!icsneo_isValidNeoDevice(device))
		return false;
		
	*can_settings_struct = device->device->settings->getMutableCANSettingsFor(netid);

	return true;
}

bool icsneo_getMutableCANFDSettingsFor(const neodevice_t* device, neonetid_t netid, CANFD_SETTINGS** canfd_settings_struct) {
	if(!icsneo_isValidNeoDevice(device))
		return false;

	*canfd_settings_struct = device->device->settings->getMutableCANFDSettingsFor(netid);

	return true;
}
