This class provides an interface to reading the image metric file:

The file format for image metrics is as follows:

Header

illumina::interop::io::read_metrics (Function that parses this information)

    byte 0: version number (3)
    byte 1: record size (8 + 2*channelCount + 2*channelCount)

Extended Header

illumina::interop::io::generic_layout<image_metric, 3> (Class that parses this information)

    byte 2: channel count (uint8)

n-Records

illumina::interop::io::layout::base_cycle_metric (Class that parses this information)

    2 bytes: lane number (uint16)
    4 bytes: tile number (uint32)
    2 bytes: cycle number (uint16)

illumina::interop::io::generic_layout<image_metric, 3> (Class that parses this information)

    2*channelCount bytes: minimum contrast (uint16)
    2*channelCount bytes: maximum contrast (uint16)
