More notes formatting

Fixing regression introduced in 1.59.0 - this time for "inline" and "block" notes.
Setting "keep_new_lines" now is effective for all note modes but "default".

Notes formatting

Adding new configuration document.notes.keep_new_lines. By default, in "float" notes modes all FB2 tags are replaced with new line character (keep_new_lines = true). If set to false new lines in floating notes will be replaced with space.

Cleaning epub generation

FIXED: Under Windows when processing books in the directory with "Send To Kindle" and "Delete After Send" enabled epub file stayed locked and delete was failing.
FIXED: page anchor could be inserted "between" paragraphs causing latest epubcheck to complain.

Spaces between tags

Do not use etree's Indent functions on fb2 - in some obscure cases this conversion loses spaces.

Debug report

Store conversion result in debug report archive too

Debug report

Completely changed behavior of global "--debug" flag - it now produces report in a form of zip archive which contains information necessary for troubleshooting. Under MyHomeLib on Windows fb2epub,.exe and fb2mobi.exe read environment variable FB2C_DEBUG. It should be set to "Yes" to facilitate report creation.

Maintenance

Switching to go 1.18.3.
Updating all dependencies.
Better handling of command line processing - report more warnings for mishandled command line.
Replacing deprecated strings.Title() with "golang.org/x/text/cases" for proper Unicode handling.

"Send To Kindle" now uses EPUB directly

Amazon backend now directly supports EPUB conversion and MOBI is being deprecated.

• remove "transfer" subcommand
• make sure Send-To-Kindle works with EPUB files
• disable Send-To-Kindle for MOBI files
• adjust fb2epub and fb2mobi accordingly for MyHomeLib support

Linting
