Update struct alignment.

In high frequency environment the allegro bigcache caused significant
memory usage overhead. This commit replaces it with something much lighter.

 ### Environment variables
 
 * `GRAPHQL_ENDPOINT` - Your GraphQL endpoint. Default: `http://127.0.0.1:9090/v1/graphql`
-* `GRAPHQL_CACHE` -  Should the query cache be enabled? Default: `false`
+* `GRAPHQL_CACHE_ENABLED` -  Should the query cache be enabled? Default: `false`
 * `GRAPHQL_CACHE_TTL` -  Cache TTL in seconds for SELECT type of queries. Default: `5`
-* `LOG_LEVEL` - Logging level. Default: `info`
-* `RETRIES_ENABLE` - Should retries be enabled? Default: `false`
-* `RETRIES_NUMBER` - Number of retries: Default: `1`
-* `RETRIES_DELAY` - Delay in retries in milliseconds. Default: `250`
+* `GRAPHQL_OUTPUT` - Output format. Default: `string`, available: `byte`, `string`, `mapstring`
+* `LOG_LEVEL` - Logging level. Default: `info` available: `debug`, `info`, `warn`, `error`
+* `GRAPHQL_RETRIES_ENABLE` - Should retries be enabled? Default: `true`
+* `GRAPHQL_RETRIES_NUMBER` - Number of retries: Default: `1`
+* `GRAPHQL_RETRIES_DELAY` - Delay in retries in milliseconds. Default: `250`
+
+### Modifiers on the fly
+
+* `gql.SetEndpoint('your-endpoint-url')` - modifies endpoint, without the need to set the environment variable
+* `gql.SetOutput('byte')` - modifies output format, without the need to set the environment variable
 
 ### Cache
 
 You have two options to enable the cache:
 
-* Use `GRAPHQL_CACHE` environment variable which will enable the cache globally. It may be desired if you want to use the cache for all queries.
+* Use `GRAPHQL_CACHE_ENABLED` environment variable which will enable the cache globally. It may be desired if you want to use the cache for all queries.
 * Add `gqlcache: true` header for your query which will enable the cache for this query only with `GRAPHQL_CACHE_TTL` TTL.
+* You can check the list of supported per-query modifiers below
 
 Example:
 
 ```go
+// following values passed as headers will modify behaviour of the query
+// and disregard settings provided via environment variables
 headers := map[string]interface{}{
   ...
-  "gqlcache": true,
+  "gqlcache": true, // sets the cache as on for this query only
+  "gqlretries": false, // disables retries for this query only
 }

-// Package go-simple-graphql is a wrapper for GraphQL queries execution.
-// It's sole purpose is to allow developer to execute queries without specific fields / types mapping
-// which can be really confusing and even impossible whilst dealing with Hasura custom generated types.
-//
-// Library supports advanced error reporting on unsuccessful queries.
-// Library also uses HTTP2 for communication with GraphQL API if it's supported by server
-
-// Environment variables:
-// GRAPHQL_ENDPOINT - GraphQL endpoint to use. Default: http://127.0.0.1:9090/v1/graphql
-// LOG_LEVEL - Log level to use. Default: INFO
-//	 					 Available log levels: DEBUG, INFO, WARN, ERROR, FATAL
