Intermediate table and new dataset for abundEstim() needed

[prairie-rex]

In the newest versions you don't allow for the output of the intermediate table where abundance is estimated bySite=TRUE.

My typical process is running a global detection for a site with multiple visits by week, and then we get abundance estimates for that week by subsetting the data and extracting it that way.

The new method: https://github.com/tmcd82070/Rdistance/blob/s6Methods/R/abundEstim.R allows for neither of those, forcing me to stay with the old version.

At minimum I need to be able to input a subsetted dataset into abundEstim() e.g. allowing for global detection function dfunc() to be used for a smaller portion of the data, and/or being able to get bySite=TRUE abundance estimates.
