Compatibility improvements.

* Added compatibility with Ian Coleman's BIP39 tool for several input formats:
    * `base6`, `base10`, `bits`, and `dice` are now compatible.
    * `hex` as an input method is already compatible if used with his tool in "raw entropy" mode.
    * `cards` is not compatible as his algorithm is complex and possibly not worth spending the time on.
* Updated MANUAL.md examples to remain accurate.
* Added a section on Compatibility with other tools to MANUAL.md.

+## Compatibility
+
+* seedtool has been tested to give the same results as [Ian Coleman's BIP39 tool](https://iancoleman.io/bip39/) for the following input methods: `base6`, `base10`, `bits`, and `dice`.
+* `hex` as an input method is already compatible if used with his tool in "raw entropy" mode.
+* `cards` is not currently compatible.
+
+The example below can be replicated using Coleman's tool and selecting the following options:
+
+* Show entropy
+* Base: 10
+* Entropy: 123456
+* Mnemonic length: 12 words
+
+```
+$ seedtool --in base10 123456 | seedtool --in hex --out bip39
