Commit Message

Add regression corpus from numpy-financial and java-xirr issues

Cash flows from closed issues where those libraries returned a wrong rate,
raised, or failed to converge, each now pinned against finance-elixir:

- numpy-financial: #44 (negative final flow), #46 (second-period outlay),
  #98 (multiple roots), #15 (vanishing flows that raised LinAlgError).
- java-xirr: #17 and #14 match Google Sheets / Excel to 8 decimals, #12
  recovers the reporter's 18.84%, and #5/#7/#10/#16 resolve series that
  raised NonconvergenceException, zero-derivative, or overflow.

Roots are checked scale-relative (NPV negligible next to the largest flow),
since a near--100% or 1e9-magnitude root leaves a non-zero absolute NPV.
