Feature request: Allow CNSR > 1 in `Surv_CNSR()`

[bundfussr]

Is your feature request related to a problem? Please describe.
CDISC states for CNSR:

It is strongly recommended to use 0 as an event indicator and positive integers as censoring indicators.

At the moment Surv_CNSR() accepts 0 and 1 only.

Describe the solution you'd like

I would suggest to enhance the function such that 0 and positive integers are accepted and positive integers are considered as censored.

Thanks for letting me know!

Can you submit a PR? In cases where CNSR is greater than 1, is it more than one subject censored or a way to code different types of censor (e.g. death from another cause, lost to followup)

Sounds good, would you like to submit a PR?
