fix: Move tests under ld_eventsource namespace (#29)

Previous distributions of this package included two packages --
ld_eventsource and testing. This top level testing namespace can
conflict with other packages. In fact, it conflicts with our own SDK.

In general this doesn't matter, but it may if:

1. You are using a build process that warns about conflicts (see [this
   issue][1])
2. You want to install the sdist on an unsupported platform and would
   like to be able to verify the tests.

To resolve this issue, we are moving the testing folder into the
ld_eventsource package. These testing files will only be included in the
sdist format. This allows for a smaller wheel size while also allowing
for flexibility with consumers.
