transpose-publishing/landscapeStudy: Peer review and preprint policies are unclear at most major journals

This release contains revisions based on feedback provided by the reviewers. Improvements to the previous version: We updated the table on co-review policies. It now includes common variants of the terms displayed. We further provide a new table with sampled phrases giving more context to the terms. We have greatly improved the documentation of our code and data. Among other things, the README.md now contains tables with descriptions for the relevant data and code files
