Last block in a "section" of generated Universal Hex in block format is not padded

[microbit-carlos]

This was done as part of the original design, where the last block doesn't need to be padded as a the End Of File record would be place immediately after.

In the current configuration the Universal Hex first "section" last block is not padded.

Lines 1294 to 1295 in 4147e22

	// TODO: This test fails because the last block for a section is not padded
	// expect(universalHexBlocks).toEqual(hexCombinedBlocks);

As the default implementation now uses only "sections" without the 512-byte blocks this issue is only present for uses actively using the block format.
