    Description copied from class: ValuesReader
    Called to initialize the column reader from a part of a page. Implementations must consume all bytes from the input stream, leaving the stream ready to read the next section of data. The underlying implementation knows how much data to read, so a length is not provided. Each page may contain several sections:
    
    repetition levels column
    definition levels column
    data column
    Overrides:
    
    initFromPage in class ValuesReader
    
    Parameters:
    
    valueCount - count of values in this page
    
    stream - an input stream containing the page data at the correct offset
    
    Throws:
    
    IOException - if there is an exception while reading from the input stream
