Full images are now read

Previous versions of Isolyzer only read the first 2048000 bytes (1000*2048) of the image, which could lead to problems with HFS partitions that are located beyond that range. Images are now read as a whole using memory mapping.

Added reporting on Master Directory Blocks inside HFS volumes

This is especially useful for extracting volumeName strings. For example, try this image:

https://archive.org/details/Macintosh_Utilities_CD-ROM_1999_1999

Unlike previous versions, Isolyzer 1.2.0 now correctly extracts the info from the Master Directory Block of the Apple_HFS partition:

<masterDirectoryBlock>
    <signature>BD</signature>
    <blockSize>12663</blockSize>
    <blockCount>12288</blockCount>
    <volumeName>Mac Utilities 99</volumeName>
</masterDirectoryBlock>
