This fixes a spurious unsigned integer overflow with invalid content:

```
src/dec/alpha_dec.c:61:44: runtime error: unsigned integer overflow: 0 -
  1 cannot be represented in type 'size_t' (aka 'unsigned long')
```

Tests

This is a collection of tests for the libwebp libraries, currently covering fuzzing through the APIs. Additional test vector coverage can be found at: https://chromium.googlesource.com/webm/libwebp-test-data

Building

Fuzzers

Follow the build instructions for libwebp, optionally adding build flags for various sanitizers (e.g., -fsanitize=address).

-DWEBP_BUILD_FUZZTEST=ON can then be used to compile the fuzzer targets:

$ cmake -B ./build -S . -DWEBP_BUILD_FUZZTEST=ON
$ make -C build
