This change adds the ability to download byte ranges
to uplinkng.
Extended the uplinkng Filesystem interface with Stat
method and an OpenOptions struct as parameter for the
Open method.
Also added a few tests for the ranged download

this was just supposed to add parallel uploads/downloads
and it does do that, but i then found a bunch of bugs
with respect to path handling that i thought i had under
control. oops.
so this adds a ton of tests and tries to make the logic
in ulloc to be more consistent. almost all of the actual
file handling bits and knowledge happens in cmd_cp now
where it should belong.
additionally, the s3 command has the behavior that if your
bucket has the file s3://bucket/file, then executing
s3 ls s3://bucket/fi returns nothing. this change makes
uplinkng match that behavior even if i don't personally
like it.
a big portion of the weirdness is the concept introduced
that i've named "directoryish", which intends to capture
the behavior that if a user copies a file to that location
then the base name of the source should be appended on
rather than a direct copy. this concept is entirely a
based on the string value and not the actual filesystem
state. hence, the cp command is responsible for checking
if local paths are actually a directory, and adding a
trailing slash if necessary to make them "directoryish".
additionally, the empty key for a bucket and the empty
string for local paths are considered "directoryish".

this implements the rm command which has to add
a Remove method to the fileystem interface and
implement it for local, remote and test filesystems.

the directory was starting to get pretty large and
it was making it hard to pick concise names for
types and variables. this moves the location
stuff into a cmd/uplinkng/ulloc package, the
filesystem stuff into a cmd/uplinkng/ulfs package,
and the testing stuff into a cmd/uplinkng/ultest
package.
this should make the remaining stuff in cmd/uplinkng
only the business logic of how to implement the
commands, rather than also including a bunch of
helper utilities and scaffolding.
