quadsing: quadrature for integrals with (fractional power like) singalarities at endpoints

@thartmann15, could you please fix merge conflicts?

quadsing: quadrature for integrals with (fractional power like) singalarities at endpoints

@thartmann15, I'm closing this. Feel free reopen the pr if you wish to continue this work.

Minor error in lambertw at -1/e for branches 0 and -1

@fredrik-johansson, I'm going to close this. I don't see similar special cases across the codebase.

Inaccurate output from ellippi in 1.2.1

Ok, now integration=1 per default. Also, regression test was added in 7123a67a

Update release to contain PR #570

Fixed with 1.3

Wrong result when integrating (weighed) Chebyshev polynomials

An attempt: #603.

Test failed using mpmath.runtests()

You should use pytest to run tests, see [docs](https://mpmath.org/doc/1.3.0/setup.html#running-tests).

Implement exp() method on mpf/mpc objects?

#250 - for sqrt

Implement exp() method on mpf/mpc objects?

I doubt it's a good idea. As it was noted above, there is no established protocol for overloading functions like exp. And you could use np.vectorize for arbitrary scalar functions:...

mpmath.mpf fails converting numpy.int64

@WarrenWeckesser, this seems to be fixed in the current master, see #679 where a regression test was added. UPD: bisected to 0249d97.
