URI conversion should be done in more robust ways

[cjmyers]

All the URI, URIprefix, namespace, displayId, and version code in the Util package is very fragile and is should be rewritten.

Here are some notes on needed improvements:

<URI prefix>/<displayId>/<version>
<namespace>/<collection>/<displayId>

SBOL 2 to 3
<namespace> = <URI prefix>
<collection> = <version>

<namespace> = <domain>
<collection> = (<URI prefix> - <domain>)/<version>

for (namespace in set of namespaces)
if <URI prefix> startsWith namespace then
<namespace> = namespace
<collection> = (<URI prefix> - <namespace>)/version
set backport version to <version>

for (namespace in set of namespaces)
if <URI prefix> startsWith namespace then
<namespace> = namespace
<collection> = (<URI prefix> - <namespace>)
set backport version to <version>

SBOL 3 to 2
<URI prefix> = <namespace>/(<collection> - <backport version>)
<displayId> = <displayId>
<version> = <backport version>
