Add mice.impute.svm() for binary variables in high-dimensional settings

[mtakahashi123]

Hi Stef, Gerko, and the mice team,

As discussed in issue #751, I am submitting this Pull Request to add the Support Vector Machine imputation method (mice.impute.svm) for binary variables.

Summary of Changes:

• Added R/mice.impute.svm.R containing the proper imputation function with bootstrapping and a robust fallback mechanism.
• Updated DESCRIPTION to include kernlab in the Suggests field.
• Updated NAMESPACE and auto-generated man/mice.impute.svm.Rd with appropriate documentation and the official DOI link to the publication.

I have run devtools::check() locally on R 4.5.0, and it passed with 0 errors | 0 warnings | 0 notes.

Thank you so much for your warm welcome and encouragement. I look forward to your review!

Best regards,

Masayoshi Takahashi, Ph.D.

@gerkovink Will you be able to check and merge this?

Some extra work I expect:

• See if this PR break anything in the current code
• Please scan roxygen in mice() and add a short line with the new function
• NEWS needs to get an entry highlighting the new functionality
• Append new contributor. I usually append to the end of the contributor list.
• Update the version number, to 3.19.{+1}
• Rebuild the site. There needs to be a new entry for the site pages
