* feat: add matrix module * fix(animations): parse transform property correctly * fix(css-animations): compute transformation value with matrix * refactor: add typings for keyframes array in style scope * fix(animations): transform regex and method invocation * fix(matrix): rewrite decomposition function * refactor: transform animations parse * test: add tests for css animation transform * refactor: move transformConverter to style-properties * lint: remove unnecessary comma * lint: remove unnecessary word in d.ts * fix(style-properties): correctly use transformConverter * fix(matrix): flat multiply affine 2d matrices cc @PanayotCankov
