Quectel EG25-G Delta Radio Firmware Upgrade support - libmts-io implementation

During testing I discrovered that EG25-G radio may lose some data during transmission
over Serial AT interface or just freezes and stops responding over Serial AT interface.

When ACK mode is not used, the radio may either return an error:

```
Expected: [+QFUPL: 24312545,fa6b], Actual: [+QFUPL: 17124608,b907

+CME ERROR: 409  // Fail to write the file
]
```

Or it may just freeze on modem_at1 interface and stop responding to AT commands:

```
8:0:34:32|TRACE|RADIO| Sending command [AT]
8:0:34:133|DEBUG|RESULT:

8:0:34:133|DEBUG|Shutting Down
```

This commit implements an alternative, ACK mode for data transmission to prevent data losses.
Data is sent in chunks and the device waits for ACK string from the radio for each chunk.
