BigInt versions of library functions & operations

[karlti]

Suggestion

TODO:
publish BigInt versions of all relevant library functions & operations

Context

say, you want to run Shor's algorithm, in the incarnation of the QDK sample "Quantum/samples/algorithms/integer-factorization" against the Resource-Estimator, to get a feeling about the resources you would need..

all library functions that are used in the sample, like "DrawRandomInt", "IsCoPrime" and operations like "EstimatePeriod" all use Int64 types.

that restricts you to factor only 'small' integers with max 19 decimal digits....

what if you want to check for an RSA 2048 bit key?

Affidavit (please fill out)

Please add ticks by placing a cross in the box:

• [x] I have searched both open and closed suggestions and proposals on this site and believe this is not a duplicate.
• [x] I believe that the spirit of this suggestion is aligned with the design principles and general vision for Q#.

Please tick all that apply:

• [x] This is not a breaking change to the Q# language design
• [ ] I or my organization would be willing to help implement and/or test this

Correction Just saw, that for some libraries like Microsoft.Quantum.Math there have been BitInt versions published as of Sept 1st :) Furthermore operation "EstimatePeriod" is an user defined operation and not a Q# library function.

sorry for the noise
