Full Changelog: v2.4.1...v2.4.2

Features

• Add array_avg array function by @Yisaer in #4109
• Add acc_max_by cumulative analytic function: returns the value tied to the greatest compare_value, latest event wins on ties by @ngjaying in #4115
• Add acc_map_agg cumulative analytic function: builds an ordered key-value array, later values overwrite by key by @ngjaying in #4115
• Add acc_min_by cumulative analytic function: returns the value tied to the smallest compare_value, consistent with acc_max_by by @Yisaer in #4119

• XSQL: reset escape state after escaped quote by @zhao Jianing in #4125
• Cast: range-check string-to-int conversions by @zhao Jianing in #4123
