Map array of binary strings to List<MultipartFile> (sngular#387)

* Map array of binary strings to List<MultipartFile>

processArray resolved simple array item types via MapperUtil.getSimpleType,
which has no binary detection, so `type: array, items: {type: string,
format: binary}` produced List<String>. Detect binary items with
ApiTool.isBinary (covers both OpenAPI 3.0 `format: binary` and 3.1
contentEncoding/contentMediaType) and map them to MultipartFile, matching
the existing scalar-property behaviour in processStringProperty.

Adds an array-of-binary property to the testSimpleBuild Document schema as a
regression test.

Fixes sngular#386
