Similar to #24 and see cryptomator/android#479

We need to increase the buffer size here as well (ByteBuffer.allocate(PAYLOAD_SIZE + GCM_TAG_SIZE))

cryptolib/src/main/java/org/cryptomator/cryptolib/v2/FileContentCryptorImpl.java

Line 78 in 9097dc3

ByteBuffer cleartextChunk = ByteBuffer.allocate(PAYLOAD_SIZE);
