v0.1.3

Fixes an issue with the truncation of end times when the user specified an end time in the future.

Improves handling for typos on the command line by reporting when there are flags left over after argument parsing.

Both promdump and promremotewrite have been updated to use golang 1.19, as well as updating their dependencies to use version 0.37 of the prometheus libraries. File reading and writing were changed to use the os module instead of the deprecated ioutil module.

Improved --help output and a new --debug flag that will be used to make the logs less chatty in future.
