Add ppmd based on LZMA SDK 22.01 (thanks to @pps83)

sounds stupid to say thanks to @myself, I simply based entire PR on some other diff that added another codec

All those functions ( pmalloc(), pfree(), CharWriter, CharWriterFunc() ) should be moved to lzbench_ppmd_compress(). They are small enough to move to the function body. Compressors.cpp is not private yard, it's public space and you should not litter it.

[pps83]

@tansy sorry for late reply. PR updated.

FYI, when I tried to use latest LZMA SDK 23.01 (instead of 22.01) I got compilation errors because lzbench already contains older lzma sdk parts (specifically 7zTypes.h, Compiler.h, Precomp.h and others are conflicting). With 22.01 at least it compiles cleanly.

when lzma is updated to 23.01, libppmd should also be updated to 23.01 at the same time

FYI @inikep

I cherry picked your commit to solve the conflicts. lzbench 2.0 will add support for ppmd soon.

[pps83]

Perhaps, would be good to update to latest 7zip/lzma sdk: https://7-zip.org/sdk.html (it's 24.09 now)

I tried lzma 24.09 but it doesn't work with ppmd based on LZMA SDK 23.01.
So in the next lzbench version we will have:

• ppmd based on LZMA SDK 23.01 (thanks to @pps83)
• lzma 23.01

[pps83]

you need to take both lzma sdk 24.09 and updated lib ppmd (I updated my libppmd fork with 24.09, works for me)
