-----------------------------------------

[~pranavsaxena] can I remind you to set the bus you want to get in into target 
version, not fix. that is only used for branches where the fix has been merged 
in; it is used for release note generation

> The method `optimisedRead` creates a buffer array of size `readBufferSize`. 
> If footerReadBufferSize is greater than readBufferSize, abfs will attempt to 
> read more data than the buffer array can hold, which causes an exception.
> Change: To avoid this, we will keep footerBufferSize = 
> min(readBufferSizeConfig, footerBufferSizeConfig)
