The time from exposure to download completion is twice as long as the exposure time.

[jctk]

Describe the bug

• When shooting with the SVBONY SV905CC, the time from exposure to download completion takes twice as long as the exposure time.
• It takes twice as long as the total exposure time to complete the sequence.

To Reproduce

1. Create and execute a Sequence with the following settings
   • Exposure 30 seconds
   • Count 5
   • Type Dark
   • Gain 200
2. the time it takes to download the data from each shot is as follows (refer to the log)
   • 29 seconds for the first shot
   • 35 seconds for the second image
   • 60 seconds for the 3rd, 4th, and 5th images. 3.
3. similarly for 60 seconds
4. the first shot took 80 secound, from the second shot, the time from exposure to completion of downloading takes twice as long as the exposure time.

Expected behavior

• Exposure time plus a few seconds from exposure to download completion.

I created a test program using only the SVBONY Camera SDK to investigate.
As it turns out, it was not a problem with the INDI driver.
It is a problem of the SDK.

The problem that it takes time to download the data taken with SVBONY Camera SDK occurs.
So I'm closing this Issue.
