Create a tool to dump an EBML file structure

[FreezyLemon]

EBML is a "binary equivalent to XML", so it should be plausible to write a small tool that converts the EBML input into a human-readable representation.

The output should be similar to XML, but obviously does not need to conform to XML specs.

The tool should be able to recognize Elements (ID, Length, Data/Value) and differentiate Master Elements from "primitives".

Something optional would be reading and validating CRC-32 inside of Master Elements.

An output example:

<EBML>
  <Master(ID 0x1A45DFA3, Size 11)>
    <Element(ID 0x4287, Size 4)>
      [0x0, 0x0, 0x0, 0x4]
    </Element>
    <!-- ... -->
  </Master>
</EBML>

Maybe even with some possible data interpretations:

<EBML>
  <Master(ID 0x1A45DFA3, Size 11)>
    <Element(ID 0x4287, Size 4)>
      [uint: 4]
      [int: 4]
      [float: 1.1e-44]
    </Element>
    <!-- ... -->
  </Master>
</EBML>

Again, the actual output format isn't that important. It just needs to be readable and should be helpful to check what's going on inside any given EBML file.
