9dea8169e0 WIA: Write all headers at the start of the file 
Gets rid of the need to seek to the end of the file
when opening a file.

The downside of this is that we waste a little space,
since we can't know in advance exactly how much
space the compressed parts of the headers will need.

e5b9e1ba1f WIA: Reuse groups when writing 
This is useful for the way Dolphin scrubs Wii discs.
The encrypted data is what gets zeroed out, but this
zeroed out data then gets decrypted before being stored,
and the resulting data does not compress well.
However, each block of decrypted scrubbed data is
identical given the same encryption key, and there's
nothing stopping us from making multiple group entries
point to the same offset in the file, so we only have
to store one copy of this data per partition.

For reference, wit zeroes out the decrypted data,
but Dolphin's WIA writer can't do this because it currently
doesn't know which parts of the disc are scrubbed.

This is also useful for things such as storing Datel discs
full of 0x55 blocks (repesenting unreadable blocks)
without compression enabled.

8da5d0c4fe Add an early version of WIABlobReader 
It can currently only read the first 0x80 bytes of a disc image,
which is enough for identifying it but not for doing anything else.

162e3be82b Show an OSD message when running a disc image with a large block size 
This is intended to catch WIA files which have been created using
wit's default parameters (40 MiB block size), once the WIA PR is
merged. The check does however also work for GCZ files – not that
I think anyone has a GCZ file with a block size that large.

04c7892b93 DiscIO: Add GameCube disc scrubbing support 
The code was actually already rather well adapted for this.
We more or less just have to skip ParseDisc and run
ParsePartitionData directly. This required the PartitionHeader
struct to be removed (which wasn't that useful anyway).

cefc2a7baa DiscIO: Fix edge case where blocks could get scrubbed accidentally 
If we start 31 KiB into a 32 KiB block and want to mark 2 KiB
of data as used, we need to mark 2 blocks as used, not just 1.

This problem is avoided when calling MarkAsUsed from
MarkAsUsedE, since MarkAsUsedE aligns to 32 KiB on its own.
Most calls to MarkAsUsed are from MarkAsUsedE, which is why
this hasn't been a noticeable problem in the past.

8a9597e32e DiscIO: Allow converting from formats other than ISO and GCZ 
The constant DESIRED_BUFFER_SIZE was determined by multiplying the
old hardcoded value 32 with the default GCZ block size 16 KiB.
Not sure if it actually is the best value, but it seems fine.
