clusters/halo.py: Rewrite electron acceleration coefficient calc
* Adopt the electron acceleration coefficient formula from [cassano2005] * Rename method "_tau_acceleration()" to "_chi_acceleration()", and rewrite * Add property "kT_merger" * Also save "kT_merger" and "chi" into halos data Signed-off-by: Aaron LI <aly@aaronly.me>
