Hi, I started porting the same file this morning and forgot to push it to github. Are you working on it? If no, then I'll try to merge our changes and get it done tonight. |

API changes: * Add `HasSum.sum_range_add`, `sum_add_tsum_nat_add'`, and `tsum_eq_zero_add'`. We had these (or stronger) results for topological groups. These versions works for monoids. * Rename `tendsto_atTop_csupr` to `tendsto_atTop_csupᵢ`, `tendsto_atBot_csupr` to `tendsto_atBot_csupᵢ`, `tendsto_atBot_cinfi` to `tendsto_atBot_cinfᵢ`, and `tendsto_atTop_cinfi` to `tendsto_atTop_cinfᵢ`. * Add a shortcut instance for `T5Space ENNReal`. * Add `ENNReal.nhdsWithin_Ioi_one_neBot`, `ENNReal.nhdsWithin_Ioi_nat_neBot`, `ENNReal.nhdsWithin_Ioi_ofNat_nebot`, and `ENNReal.nhdsWithin_Iio_neBot`. * Add `ENNReal.hasBasis_nhds_of_ne_top` and `ENNReal.hasBasis_nhds_of_ne_top'`. * Add `ENNReal.binfᵢ_le_nhds` and `ENNReal.tendsto_nhds_of_Icc`. * Use `Real.nnabs` instead of `nnnorm` to avoid dependency on `analysis.normed.group.basic` (forward-port of leanprover-community/mathlib#18562). * Add `ENNReal.tsum_eq_limsup_sum_nat`. * Add `ENNReal.tsum_comp_le_tsum_of_injective`, `ENNReal.tsum_le_tsum_comp_of_surjective`, use them to golf some proofs. * Add `ENNReal.tsum_bunionᵢ_le_tsum`, `ENNReal.tsum_unionᵢ_le_tsum`. We had versions of these lemmas for finite collections. The proofs for infinite collections are simpler. Most of these changes were done to fix some long proofs: it was easier for me (@urkud) to add supporting lemmas and golf the proof than to fix the original code. Co-authored-by: Yury G.
