Create TestFileUtils.getMD5Hash to compare binary files

[labkey-tchad]

Rationale

IntelliJ recommended using Files.readString instead of Files.readAllBytes. However, Files.readString is more strict about the file structure. FileAttachmentColumnTest is failing because it is using TestFileUtils.getFileContents for various non-text files (e.g. zip and pdf). This strictness is useful for most scenarios, so I've created a new method to compare whether two files are equal (TestFileUtils.getMD5Hash).

java.lang.RuntimeException: java.nio.charset.MalformedInputException: Input length = 1
