Asynchronous and synchronous resets

two_resets has two flops that capture d on every rising edge of clk:

• q_async has an asynchronous, active-low reset, rst_n: it clears the moment rst_n falls, without waiting for the clock.
• q_sync has a synchronous, active-high reset, srst: it clears on a rising edge where srst is 1, and ignores srst between edges.

The current design.sv gets both wrong. Fix it.
