Detailed Description
Agile Modbus software package common source file.

use:
Users need to implement the `send data`, `wait for data reception to end` and `clear the receive buffer` functions of the hardware interface.
- Host:
1. `agile_modbus_rtu_init` / `agile_modbus_tcp_init` initializes `RTU/TCP` environment
2. `agile_modbus_set_slave` sets the slave address
3. `Clear the receive cache`
4. `agile_modbus_serialize_xxx` package request data
5. `Send data`
6. `Waiting for data reception to end`
7. `agile_modbus_deserialize_xxx` Parse response data
8. Data processed by users
- Slave machine:
1. Implement the `agile_modbus_slave_callback_t` type callback function
2. `agile_modbus_rtu_init` / `agile_modbus_tcp_init` initializes `RTU/TCP` environment
3. `agile_modbus_set_slave` sets the slave address
4. `Waiting for data reception to end`
5. `agile_modbus_slave_handle` processes request data
6. `Clear the receive buffer` (optional)
7. `Send data`- Attention
