Add documentation of the new hex output formats.
Thanks to text contributed by Tom LeMense, the manual now includes
documentation of the hex formats he contributed. This also includes some
updated text on the ORG directive. Only minor editorial changes vary the
text from Tom's original.

80 >This ASCII format consists of a series of CR+LF terminated "records" of ASCII | |
81 text. Each record has the following structure: a start-of-record character | |
82 ":", a two-digit ASCII hex byte count, a four-digit ASCII hex address, a two- | |
83 digit ASCII hex record type, an optional sequence of two-digit ASCII hex data | |
84 values, and a two-digit ASCII hex checksum. The LW tool chain issues only 00, | |
85 and 01 Intel Hex record types. Data records are limited to maximum of 16 | |
86 data bytes in length, and paragraph alignment of addresses is favored. The | |
87 address sequence of the Intel hex records directly follows that of the source | |
88 file; multiple ORG directives in the source code may result in out-of-sequence | |
89 addresses in the Intel Hex output. </P | |
