Make unicorns grok errors and warnings. Added unicorn formatted error and warning output and also a framework to handle errors which know which character position in the line they occurred in.

>A DECB binary is compatible with the LOADM command in Disk Extended
Color Basic on the CoCo. They are also compatible with CLOADM from Extended
Color Basic. These binaries include the load address of the binary as well
as encoding an execution address. These binaries may contain multiple loadable
sections, each of which has its own load address.</P
><P
>Each binary starts with a preamble. Each preamble is five bytes long. The
first byte is zero. The next two bytes specify the number of bytes to load
and the last two bytes specify the address to load the bytes at. Then, a
string of bytes follows. After this string of bytes, there may be another
preamble or a postamble. A postamble is also five bytes in length. The first
byte of the postamble is $FF, the next two are zero, and the last two are
the execution address for the binary.</P

>Both LWASM and LWLINK can output this format.</P
