* Use "lib" in tsconfigs instead of "target".
Only add "dom" to libraries that need it. This is determined by a script, so many libraries that have "dom" maybe should not.
* Update new-package and readme
* Add back "target" where necessary
* d3-dsv: Added new definitions and tests correspondinf to d3-dsv module (v 1.0.1) of D3 version 4. Moved legacy definitions and tests into new sub folder v0. These are no longer relevant, as they do not reflect d3-dsv package at all. There should be no dependencies on them.
* d3-request: Added definitions for module and related shape tests.
