Dsptools examples (#457)

Browse Source 
* Add c test files for DSPTools example

* Update tests Makefile to build DSPTools c tests

* Add DSPTools example configs to ConfigMixins and RocketConfigs

* Add dsptools and rocket-dsptools as dependancies for example

* Add Scala implementations of DSPTools test blocks

* Clean up GenericFIR scala

* Modify dsptools blocks and mixins to match 'CanHave' when adding peripherial

* Update documentation, will need reworking once FIR is characterized as fixed point

* Update naming of Passthrough to Streaming Passthrough. Update naming of Thing to Chain and remove old Chain

* Fix capitalization in docs (#419)

* Docummentation update for clarity and to explain how this can be applied to a generalized block

* Some refactoring to get dsptools working with these examples

* Oops, old files crept in
