FitsBlockBoundaries

Class to hold block boundaries. These values are computed at first file scan then encoded to be broadcasted to all datanodes through the Hadoop configuration block.

headerStart: : (Long) Starting byte of the header blocks
dataStart: : (Long) Starting byte of the data blocks
dataStop: : (Long) Last byte of non-zero data (could be in a middle of a data block)
blockStop: : (Long) Last byte of the data blocks (data blocks are multiple of 2880 bytes)

Register the boundaries of the HDU in the Hadoop configuration.
Register the boundaries of the HDU in the Hadoop configuration. By doing this, we broadcast the values to the executors. It is sent as a long String, and can be read properly afterwards using retrieveBlockBoundaries. Make sure you use the same separators.
