biology/emboss: Add "emboss" command in ${LOCALBASE}/bin

Standard emboss commands are installed under a special prefix because
of multiple conflicts.  The emboss command turns the standard commands
into subcommands, so no special PATH is needed.

    /usr/local/emboss/bin/needle [args]

can be run as

    emboss needle [args]

+/***************************************************************************
+ *  Description:
+ *      Wrapper to turn emboss commands into subcommands.  The emboss suite
+ *      contains executables that conflict with multiple other software
+ *      packages and therefore cannot be safely installed directly under a
+ *      standard prefix.  This wrapper can be installed under the standard
+ *      PATH and used to to execute emboss commands installed under a
+ *      private prefix, without altering PATH, activating a special
+ *      environment, opening a container, etc.  This sub-command paradigm
+ *      is already familiar to bioinformaticians thanks to other suites
+ *      like samtools, bedtools, etc.
+ *
+ *      Example:
+ *
+ *          emboss seqret args
+ *
+ *      instead of one of the following:
+ *
+ *          prefix/bin/seqret args
+ *
+ *          env PATH=prefix/bin:$PATH seqret args
+ *
+ *          conda activate emboss
+ *          seqret args
+ *
+ *  Arguments:
+ *      The full emboss command you would use if it were in PATH.
+ *
+ *  Compile with EMBOSS_PREFIX set to the parent of the bin directory
+ *  containing the emboss binaries.
+ *
+ *  History: 
+ *  Date        Name        Modification
+ *  2021-09-13  Jason Bacon Begin
