Add 64 bit soundfont support

[drbscl]

Description

This PR adds soundfont support to 64-bit systems, by fixing a limitation in the soundfont library.

The problem was due to the soundfont library storing addresses in a 32-bit DWORD, which causes problems in systems with 64-bit addresses.

Note: I have only been able to test the RG35XX build, since this is the only hardware I have on hand to test with. I recommend others test this change on other hardware before promoting this to a stable release.

Type of change

• Fixes [BUG] - Can't import a soundfont on rg35xx+ #201
• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Test Configuration:

• Hardware: RG34XX SP (With RG35XX build, these devices all have the same SoC)
• Test steps: Open a project that includes a soundfont, then create & play new phrases with instruments using that soundfont.

Checklist:

• I have performed a self-review of my code
• I have commented particularly in hard-to-understand areas
• I have updated CHANGELOG
• I have updated docs/wiki/What-is-LittlePiggyTracker.md reflecting my changes
• I have version bumped in sources/Application/Model/Project.h
• My changes generate no new warnings (build without your change then apply your change to check this)

@djdiskmachine I'm not entirely sure how I should update the CHANGELOG since bacon3 has already been released.

[djdiskmachine]

Wow exciting!
I can try it out on my machine and report back :)

[djdiskmachine]

The next release will be 1.6.0, if it works good I'll add it to the next candidate :)

[drbscl]

Will fix the formatting & build regression for windows

[drbscl]

Not sure how you want the RC to be named, so I'm happy to change as needed

[drbscl]

As above, I'm happy to change to indicate it's RC

[djdiskmachine]

Great, let's go for 1.6.0-bacon0 💪🥳

Hmm, my editor's autoformatting has gone a bit aggressive, sorry about that. I can revert if you need me to.

[djdiskmachine]

Sorry about the over-enthusiastic clang-format job. As you know the formatting is really all over the place and I made the line-by-line format so that not every commit would be impossible to review.
Did you find the commit hook I made?
I'll try to review proper this evening and give things a test run.

For MacOS I can attest that it does appear to work!
I can load the attached project, start playing and it plays the song fine. Great success!
I'll have another look at it on an Ubuntu machine this evening, but looks very promising.
Great work! =)

I did run clang-format for all of my changed lines after I noticed the instructions, then setup the hook, so not 100% sure why we're still getting a formatting issue.

Will look into it when I get some time.

[drbscl]

Ok, I've run the formatter again, hopefully it should pass CI this time.

[djdiskmachine]

Thank you very very much, It's really great to have future-proofed SoundFont support! =)

[drbscl]

No problem, glad to be of assistance!
