TopPIC for Debian

The ext/xml2json directory was kept, unlike the other directories below, because
the corresponding software is not available in the Debian repositories.

The pwiz library code was removed in favor of the libpwizlite package that I have
crafted.

The boost code needed by the pwiz library is also available in the libpwizlite
package.

The hts library is available in Debian.
