feat(NumberTheory/LSeries/Deriv): derivatives of L-series (#11245) This adds a file Mathlib.NumberTheory.LSeries.Deriv that contains results on differentiability and derivatives of L-series, including the fact that the L-series is holomorphic on its right half-plane of absolute convergence. See this thread on Zulip.
