CSP commands related to file operation may take time to process. Therefore, a dedicated thread is provided to handle CSP packets sequentially via a glib-2.0 queue. This commit only adds the framework for this functionality. Additionally, the CSP port for file-related commands is set to `13` to maintain consistency with MAIN and ADCS.

Fixes a invalid command offset for command ID argument. Signed-off-by: Takuya Sasaki <[email protected]>
This commit adds the open file command needed for file upload from the Ground System to SC-Sat1. This command includes the session ID and the target file name. On the SC-Sat1 side, it associates the session ID with the file name and opens the target file with write permissions. If the target file does not exist, it will be newly created. The session ID will be included in subsequent Data Packets (DATA). For uploads, the file that can be opened is defined by UPLOAD_MAX_SESSION. This implementation also uses `g_slist` for session management; however, since upload commands are processed sequentially from the CSP server thread, mutual exclusion is not implemented at this time. In a subsequent commit, the DATA and CLOSE commands will also be added. Signed-off-by: Takuya Sasaki <[email protected]>
This commit adds the write data command needed for file upload from the Ground System to SC-Sat1. This command includes the session ID indicating the file opened with OPEN command, the write offset, the size, and the actual datae. This command is expected to be sent continuously, so sending a reply telemetry each time would waste downlink bandwidth and could cause collisions with the upload command on the CAN bus. Therefore, a mechanism has been implemented to stack a certain number of results and return a response only when a set threshold is reached. The maximum length of the data is set to 200 bytes, considering the uplink frame limit of the SRS-3. Signed-off-by: Takuya Sasaki <[email protected]>
This commit adds the close file command needed for file upload from the Ground System to SC-Sat1. This command closes the file that was written using the OPEN and DATA commands, and it releases the session management information. Signed-off-by: Takuya Sasaki <[email protected]>

This PR adds the file upload command handler for Zero.
The file upload commands and telemetry are same as the MAIN/ADCS board.
