fix(packages): update ACLPC_CHECKSUM after FastLED org transfer

[zackees]

Problem

The `FastLED/framework-arduino-lpc8xx` repository was org-transferred from `zackees/` to `FastLED/` on 2026-06-28. GitHub regenerates archive metadata after ownership changes (the archive's top-level directory name flips owner in the tarball prefix), so the SHA256 of the archive at

https://github.com/FastLED/framework-arduino-lpc8xx/archive/50d76e0d63c2d2a2b365b29de47100d93c530c83.tar.gz

changed even though the git tree is byte-identical. Every `bash compile lpc845brk` on the FastLED side now aborts with:

```
build error: package error: checksum mismatch for
...framework-arduino-lpc8xx...
50d76e0d63c2d2a2b365b29de47100d93c530c83.tar.gz:
expected e6bbcc3392ae9da44c5c92268d7cd953770e0011fcf285561104633e36087428,
got e64f0cb81ab1673e05c2a63b7b4548c1373c9ba885413d2a2351bbfae160fbec
```

Fix

Update `ACLPC_CHECKSUM` to the current archive SHA256:

e64f0cb81ab1673e05c2a63b7b4548c1373c9ba885413d2a2351bbfae160fbec

Verification

Manually confirmed on 2026-07-01 against a fresh fbuild-cache download. With this fix (applied via binary-patch of the installed fbuild.exe to prove the checksum-only change works), `bash compile lpc845brk --examples AutoResearch --build-flag "-DFASTLED_LPC_PWM_DMA=1"` on FastLED master completes end-to-end:

```
Board: NXP LPC845-BRK / LPC845 @ 24MHz
Toolchain: arm-none-eabi-gcc 15.2.1
Flash: 53.52KB / 64.00KB (83.6%)
RAM: 9.07KB / 16.00KB (56.7%)
build succeeded in 212.2s
