Load pre-computed MLB model datasets from the SportsDataverse data repo

Season-level loaders for the modeled MLB datasets published on the sportsdataverse-data releases, mirroring sportsdataverse-py's load_mlb_* loader surface:

• load_mlb_expected_stats() / load_mlb_expected_hr() / load_mlb_batter_projection() – hitting models (xBA/xwOBA-style expected stats, expected home runs, and blended batter projections).

• load_mlb_stuff_plus() / load_mlb_command_plus() / load_mlb_xera() – pitching models (Stuff+, Command+, and expected ERA).

• load_mlb_oaa() / load_mlb_catcher_framing() – fielding models (outs above average and catcher framing runs).

• load_mlb_re24_matrix() / load_mlb_we_table() / load_mlb_wpa() – game-state references (run-expectancy matrix, win-expectancy table, and per-play win probability added).

Coverage starts in 2015 (2016 for load_mlb_batter_projection()) and runs through the most recent season.
