fix: remove default export in favor of named exports

Fixes #129

microbundle is not happy with the mixing of default and named exports. It seems the easiest thing to do here is make the default export a named export.

This is probably a breaking change from v7.0.0, but since it was released not long ago and not really working all that well anyways, I'm just calling this a fix and assuming this named export thing should've been a breaking change that landed in v7.0.0.

This is probably a violation of SEMVER in a strict sense, so I apologize to anyone who already made workarounds for what was in v7.0.0.

 ## API Docs:
 
+As of Version 7, there is no longer a default import. The `find` function should be used instead.
+
 As of Version 5, the API now returns a list of possible timezones. There are certain coordinates where the timekeeping method will depend on the person you ask. Also, another case where 2 or more timezones could be returned is when a request is made with a coordinate that happens to be exactly on the border between two or more timezones.
 
-### geoTz(lat, lon)
+### find(lat, lon)
 
 Returns the timezone names found at `lat`, `lon`.  The timezone names will be the timezone identifiers as defined in the [timezone database](https://www.iana.org/time-zones).  The underlying geographic data is obtained from the [timezone-boudary-builder](https://github.com/evansiroky/timezone-boundary-builder) project.
 
 This library does an exact geographic lookup which has tradeoffs.  It is perhaps a little bit slower that other libraries, has a larger installation size on disk and cannot be used in the browser.  However, the results are more accurate than other libraries that compromise by approximating the lookup of the data.
 
 The data is indexed for fast analysis by caching subregions of geographic data when a precise lookup is needed.
 
-### geoTz.setCache(options)

 By default, geoTz lazy-loads exact lookup data into an unexpiring cache. The `setCache` method can be used to change the caching behavior using the following options:
