Text output

Unlike the other spatial temporal types, asText takes no maxdecimaldigits argument here: a pcpoint or pcpatch prints as the hex-WKB of its serialized form, which has no decimal places to round. The same holds for th3index.

Text output is the safe subset of the textual surface: there is no tpcpointFromText / tpcpatchFromText, because pgPointCloud's pcpoint_in / pcpatch_in accept hex-WKB only and the schema is not reconstructible from the text form. For round-trip use asBinary / asHexWKB with their matching parse functions.
