[Feature] Handle "-" strand gene translation

The strand column in the gene map file was previously ignored. Now the "-" strand genes are correctly reverse-complemented before translation. Thanks @dnanto for the contribution.

[Feature] Update SARS-CoV-2 clade schema

The schema that illustrates the tree of SARS-CoV-2 clades on the main page of Nextclade Web was updated to account for recent clade changes.

[Fix] Center mutation markers in sequence views

Previously the mutation markers in sequence views in results table of Nextclade Web were anchored to their position in the sequence view on their left edge. They are now correctly centered around their position, such that the center of marker is at the corresponding position in the sequence.

[Fix] Correct exit codes

Nextclade CLI and Nextalign CLI could sometime exit with incorrect exit code. This has been fixed.

[Fix] Correctly handle empty peptides

The alignment algorithm in Nextclade CLI and Nextalign CLI could sometimes produce translation that is longer than expected, when the translated sequence is empty. Now the empty peptides are discarded and a warning is issued.

[Fix] Ensure array boundaries

In rare cases Nextclade and Nextalign algorithms could sometimes read past the end of arrays, which previously went undetected. This is now fixed.
