Subject: [PATCH] rastertopclx.c: Fix infinite loop caused by crafted file
Infinite loop happened because of crafted input raster file, which led
into heap buffer overflow of `CompressBuf` array.
Based on comments there should be always some `count` when compressing
the data, and processing of crafted file ended with offset and count
being 0.
Fixes CVE-2025-64524
