New models 2024-07-11

[nordzilla]

Adds the following new model files:

• enlt (1.0a1)
• hren (1.0a1)
• lten (1.0a3)
• lven (1.0a1)
• slen (1.1a1)

@nordzilla I don't see lt-en and sl-en eval scores updated. You probably need to delete the evals folders for those language pairs to retrigger evaluation

[nordzilla]

Trying this again with two new commits that delete the lten and slen directories in evaluations.
