Read Mode - disappeared from the INDI GUI menu

[JBielanski]

After update to new INDI version from git, Read Mode disappeared from menu.
Number of modes for QHY600 read properly. Following things does not working:

• indigui do not display 'Read Mode', only in logs is displayed maximum number of read modes and current read mode
• read mode is not read from camera config file
• problem appear for QHY600M camera (probably for other QHYs which supported changing 'read mode' will be similar)

Nothing recently changed AFAIK. ReadModeNP is defined once HasReadMode is set to true. It is only set to true if number of read modes > 1. How many read modes does your camera have?

This code is doing this check:

ret = GetQHYCCDNumberOfReadModes(m_CameraHandle, &readModes);
if (ret == QHYCCD_SUCCESS && readModes > 1)
{
 HasReadMode = true;
 LOGF_INFO("Number of read modes: %zu", readModes);
}

On evening I will check the code. I am planning to find commit where everything works well and from this point I will start looking for commit where problem appear.
