[BUG/REGRESSION] 2ch.hk parsing is broken

[K1rakishou]

Namely here: 551c97d#diff-a6ea4f84b562cfcf22f06c879c78fda8R215

There is no "break" operator after md5 string is extracted so it skips the next name which breaks everything.

Also, 2ch.hk already sends the md5 parameter as a normal string (it's not base64 encoded) so we don't need to decode it.

public Builder fileHash(String fileHash) {
    if (!TextUtils.isEmpty(fileHash)) {
        this.fileHash = StringUtils.decodeBase64(fileHash);
    }

    return this;
 }
